Hello,
I have a HP Proliant ML30 Gen9 server and I have installed an Intel X520-DA2 NIC. With the default Proxmox 8 kernel, 6.2.16-4-pve, the ixgbe driver fails to load with the following errors:

[ 1.709221] ixgbe 0000:06:00.0: enabling device (0140 -> 0142)
[ 1.709498] ixgbe 0000:06:00.0: BAR 0: can't reserve [mem 0x80100000-0x8017ffff 64bit]
[ 1.709500] ixgbe 0000:06:00.0: pci_request_selected_regions failed 0xfffffff0
[ 1.709895] ixgbe: probe of 0000:06:00.0 failed with error -16

[ 1.710247] ixgbe 0000:06:00.1: enabling device (0140 -> 0142)
[ 1.710306] ixgbe 0000:06:00.1: BAR 0: can't reserve [mem 0x80180000-0x801fffff 64bit]
[ 1.710308] ixgbe 0000:06:00.1: pci_request_selected_regions failed 0xfffffff0
[ 1.710384] ixgbe: probe of 0000:06:00.1 failed with error -16

I have tried many combinations for the pci kernel parameters but it didn't help.
As a workaround I can remove the PCIe bridge where the NIC is installed and then rescan the PCI bus but I intend to make this NIC my primary one and this WA is cumbersome.

echo 1 > /sys/bus/pci/devices/0000\:00\:1c.4/remove
echo 1 > /sys/bus/pci/rescan

Currently, I have downgraded the Linux kernel to 6.1.10 and it works just fine. Same with kernel 5.15.108 on Proxmox 7.
Attached are the dumps from lspci and PCI related messages from dmesg for both kernel 6.1.10 and 6.2.16-4.

Thank you.

I'm also having these same issues. removing the bridge and rescanning doesn't work for me. Downgrading the kernel did though; Thanks for that!

Maybe just an additional info:

Seems to me like an issue related only to x520 cards.

Because my x550-t2 work without any issues with 6.2.16-5.

@manseb
As you have an X520-DA2 from intel, did you tryed to update that card to the newest firmware?
Called "nvm-update-utulity" and is available from intel directly on their driver page.

Chances are high that you only need a newer firmware, because from what i seen on the open-source ixgbe driver is, that sometimes they fix/add features and if they need additional fixes in the firmware itself, intel releases a newer firmware then.

That took me once forever to find out, because intel provides no changelogs and i wanted to know exactly what changed in the nvm-firmware, so i digged forever, till i found out that the nvm firmware changes belong simply to the ixgbe driver changes from intel (which gets adopted in the open-source ixgbe driver either).

@DemiNe0
Same for you.


Sidenote for everyone else:
If your adapters are onboard modules (on the mainboard directly).
Do not update nvm-firmware!!!
Because you will render your intel x520/x550/x710 nic into a debug mode!!!
This means your card won't work anymore until you flash it back!
If your onboard nic has 2 ports, only one will stuck into a debug mode, while the second will work!
Nvm util will always offer you to make a backup before flashing, do the backup and safe that backup to a good place, because issues might be not visible first!!!

For everyone one else with an intel branded nic, from intel, that's a save update and you don't actually need a Backup, because you can download simply any firmware version from intel.

However, i don't give a guarantee that the x520 will work after an update, just that it might be the case, or the issue.
But it may also be indeed a bug in the 6.2 kernel in regarding to x520 nics.

Cheers :)
 
I also have the same issues with my x520-DA cards running on some supermicro x9 motherboards.



For anyone else that runs into this, you can follow these steps to rollback/install the older known working 6.1.10-1-pve kernel.

First check and see what kernels you have installed by running.
proxmox-boot-tool kernel list

You should see an output similar to this, note in my case this was a fresh install so it only had the 6.2.16 kernels on the system.
Code: 
root@PVE-04:~# proxmox-boot-tool kernel list
Manually selected kernels:
None.

Automatically selected kernels:
6.2.16-3-pve
6.2.16-5-pve


If you don't have the older kernel, you can install it by running
apt install pve-kernel-6.1

Then you can switch the kernel over by running proxmox-boot-tool kernel pin 6.1.10-1-pve and press y and enter to confirm then reboot.

After reboot you can check the current running kernel with `uname -a` and you should see an output like this.
Code: 
root@PVE-04:~# uname -a
Linux PVE-04 6.1.10-1-pve #1 SMP PREEMPT_DYNAMIC PVE 6.1.10-1 (2023-02-07T13:10Z) x86_64 GNU/Linux

nvm-update-utility doesn't work with the x520 cards unfortunately.

Oh that's stupid, im sorry!
I thought all 500 series have updatable firmware:-(

Code: 
Alright I solved it for me without "pci=realloc=off" or any patches with a Poweredge R920

In BIOS under "Integrated Devices"

"SR-IOV Global Enable" = ENABLE

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1245938

There are a lot of results i found on google, with that exact same issue.

But none of those results have an solution...

Maybe this is interesting:
https://gist.github.com/ixs/dbaac42...malink_comment_id=4639253#gistcomment-4639253
But this isn't a fix, just a stupid script to allow the use of any sfp receivers.

However, sorry, but can't help.
 
Honestly, I think it's just a matter of waiting for Intel to make a set of ixgbe drivers for the 6.2 kernel.... Or maybe we'll luck out with 6.3? :D

Can you passthrough the adapter to a vm to test with newer kernel?
Or simply boot an live iso or sth?

Then you could find out already today if an upcoming kernel fixes that issue, instead of waiting :)

Can you check your BIOS?

Press F9 to BIOS (RBSU), and Press CTR+A (Hidden menu will appear at the bottom "Service Options"):
- "Service Options" > "PCI Express 64bit BAR Support" > "Enabled"

Good news! For me, at least. :)
Here are the steps I used to make my Intel X520 work under kernel 6.2.x:

1. Check the 64bit BAR support in the BIOS as described by @emunt6 (your system might be different)

2. Download Intel's complete driver pack from here

3. Extract BOOTUTIL64E.EFI from <archive>/APPS/BootUtil/EFI2_x64 and copy it to an USB stick. (I did this since I intended to work in the EFI Shell, as read here)

4. Once in the EFI Shell select the USB stick (fs0 in my case):
> fs0:

5. List all supported devices:
> BOOTUTIL64E.EFI -E

Note:
With X520 you should see 2 NICs. If you have more NICs listed update the commands below to work only on the relevant device(s).

6. Enable flashing on all devices (not sure if it's needed by the next steps but I did it anyway)
> BOOTUTIL64E.EFI -ALL -FLASHENABLE

7. Reboot the system back to EFI shell

8. Enable 64bit BAR addressing on the NICs and reboot afterwards
BOOTUTIL64E.EFI -ALL -64e

9. The ixgbe driver should load under kernel 6.2.x.

Good luck!
 
@manseb, @DemiNe0, @D4M, could you attach a complete dmesg log where this fails? Ideally, open a new report at https://bugzilla.kernel.org, attach them there, and send the URL to bjorn@helgaas.com and linux-pci@vger.kernel.org (make sure the email is plain text, no HTML, etc, because vger rejects stuff like that).

It seems likely that I broke something with this change, which appeared in v6.2: 07eab0901ede ("efi/x86: Remove EfiMemoryMappedIO from E820 map"), and I'd like to fix that. This should not require kernel parameters, BIOS setting changes, firmware updates, driver updates, etc.
 
This thread is marked [SOLVED]. I think that's wrong, but I don't know how to change it. Comment #10 has a workaround, but it doesn't fix the underlying kernel problem.
 
I find it sad, that no one of the affected is (seemingly) interested in / willing to help(ing) a maintainer to troubleshoot this. :(
 
Quick note - in case it helps someone else ? I just rented a new box from OVH yesterday that I'm setting up for a client, an AMD_Epyc based 16-core with 256gb ram on a supermicro board - and the stock install of Proxmox 7 using OVH template was great, but once I did an in-place upgrade to Proxmox8 and got the newer kernel, there was a error logged in dmesg (approx - - ixgbe - probe error -5) and then the interface is absent / not functional and I have no network access, can only get onto the host via remote KVM access. I think from the sound of it I could fix this if I get an older kernel pinned as a workaround. Kind of a hassle but that is life. I sometimes thought Intel did better than this in terms of letting busted driver updates out the door. sigh.

Tim
 
Oh, wow, thank you. That looks a tiny bit fiddley. Do you think - if I just sit on Proxmox7 for a few months and upgrade to Proxmox8 later, get new kernel (not right away) - the issue will ?probably? be sorted in kernel by then? OR otherwise I guess I could maybe do the proxmox 7>8 upgrade, but make sure to pin the kernel at the less-current release as a stopgap workaround, and only do update 'later / months down road' once the dust settles on this topic?

ie, I am not sure I am super keen to do a custom kernel patch>compile here as a workaround.

thank you for the feedback! It is greatly appreciated!

Tim
 
I totally understand not wanting to deal with a custom kernel. If it's practical for you to post the complete dmesg log (booted with "efi=debug" if possible), I should be able to tell whether it's the same issue. You can attach it to the existing bugzilla.

I suggest asking the Proxmox maintainers to backport 070909e56a7d ("x86/pci: Reserve ECAM if BIOS didn't include it in PNP0C02 _CRS"), which has been applied upstream and will appear in v6.8.
 
Hi, I just reinstalled OVH Box with Proxmox-7 template
did upgrade to 8 in-place
then pinned it to Kernel
6.1.10-1-pve
thinking this would let me boot with network / as per this thread
rebooted
no joy, network error, get KVM to get access, capture dmesg to text file
reboot on rescue mode > get access to pull the dmesg text file
see below for dmesg

not sure if this tells you anything helpful or not.

I did not adjust flags on the boot / yet. right now the thing is not bootable / except rescue mode and then chroot captive root environment.
