4.15 based test kernel for PVE 5.x available

Interesting enough everything seemed fine on our new(er) hardware until I started optimizing BIOS settings for our workload. Using HPE's document to optimize for low latency recommends disabling a few features that caused these kernel panics for me.

The relevant settings are:
  • Intel Virtualization Technology -> disabled
  • Intel Hyperthreading Options -> disabled
  • Intel Turbo Boost Technology -> disabled
  • Intel VT-d -> disabled
What's odd though is I have to keep them all enabled since pve-kernel 4.15.18 while 4.15.17 was fine with these disabled.

(We use 3 nodes just for storage with a Proxmox install to simplify the CEPH installation process, otherwise these settings obviously should be enabled except for Hyper Threading perhaps)

Perhaps someone else running into this issue might want to check these settings, I'll leave them enabled for now.

regards,
Menno

That is very very strange, with all those virtualization flags disabled you should have been never able to boot any VM with us (at least if you do not set 'kvm' manually to off)..
Please never turn them off.

Meaning that it's always there, just a different (higher/lesser) likely chance to trigger it... Or even a HW/Chipset problem.

hmm your eeprom settings dump does not looks like you have a earlier problematic power feature enabled.

Have you tried disabling some offloading features? Often they're the cause of such hangs with specific chipsets:
Code: 
ethtool -Kenp0s31f6 gso off gro off tso off
(may imply some performance degradation as now the CPU must do this work)
 
we have 5 systems at the moment with this intel NIC and ProxmoxVE.
Meaning that it's always there, just a different (higher/lesser) likely chance to trigger it...

the system that crashed 2 days ago was running pve-kernel-4.13.16-2-pve until 3 days ago

thanks, will try this!

Hello,
I also have the same problem with 2x Xeon e5 2680v2 on supermicro x9drw-if, latest bios and pve.
Crashes with the same message, additionally I have one of the 10g links (x520-da) flapping since.
However, removing the Intel-Microcode package seems to hhav stabilized it a bit.
 
Hello Proxmox Team.

Have this issue been resolved in the latest kernel update? I mean from what I can read here is that only Intel network cards have this problem.

This is a blocking issue for us as we cannot upgrade our environment until we get a green light that the kernel panic errors no longer happen when host machine have Intel NICs instaled.

Than you!

So we've just run into the same issue with a SuperMicro system as well, having Intel i210 NICs installed and Kernel pve-kernel-4.15.18-7-pve: 4.15.18-27 running.

As the hardware is provided by a managed service we're currently asking them to install the most recent NIC firmware, but any ideas from the Proxmox team on how to solve this in addition?

The system was running rock solid for about 10 months now with always the latest V4.4 installed, but in order to stay within support we've decided to upgrade to 5.x. :confused:

I'll try to post crashlogs as soon as we can access the OS again...
 
Unfortunately the logs have been not stored, so we currently don't have any further details :confused:

So we'll adjust the log retention and try to have more information available when it crashes the next time...
 
Hi,

All 3 nodes are up to date. No Ceph, no ZFS. Feel free to ask if more informations needed

have a good day

guys,
we've setup two more nodes....
these two are identycal DL680 gen8.

done fresh install using downloaded .iso image,
operated all updates (on these units we've an active subscription!)

then set units as cluster members ad after some "blank" runtime days,
moved some VMs to the new nodes (these are the newer nodes then we've moved there the most expensive VMs!)

all seems to run fine for many ours (i think one or two full days at max!)
then users started to report extremely slow response from the terminal server and really long query response time from MySQL linux VM!

after some rapid checks,
we've moved VMs back to the older nodes (still running 4.13.x kernel!)

then magically issue seems to have solved, normal response time from both VMs....

actually rolled back units to 4.13.x kernel,
then restarted units and after some testing time, moved VMs back to newer nodes!

now all running fine!
our cluster updates have been locked to 4.13.x kernel branch!!

waiting suggestions or any other information may come from you all!

best regards,

Francesco
 
Hi everyone!
i have a problem with lan interface e100 on my pfsense

I too run opnsense in Prox. I have the virtual nics set as E1000. I also find that during high traffic scenarios such as Torrents skype call video streaming, downloading the WAN gateway will just drop. It then take a

Hi. This is quite an old Thread, started well over a year ago. At many problems reported are not valid anymore. Maybe it's best to start a new thread with your specific issue.

You could try to disable some offloading, but that may reduce general performance a bit:
Code: 
ethtool -K eth0 gso off gro off tso off
but could be worth a test
