Opt-in Linux 6.5 Kernel with ZFS 2.2 for Proxmox VE 8 available on test & no-subscription

Hang on 'loading initial ramdisk' also apply to Dell T140. It does not seem to be a network issue (only)

I remember an error with an early 5.15 Kernel which prevents booting the Dell T140 because of an 'could not import rpool' error. it was a problem with the disk controller on this device.

New kernel today on T340 :
6.5.11-7 -> Hang
6.2.16-20 -> Boot OK

That was obvious, because 6.5.11-6 -> 6.5.11-7 reactivated the simplefb (simple framebuffer) and didn't change anything about the Dell Problem.
I have 4 Dells with old kernel which i cannot reboot via SSH at the moment. I am on tenterhooks.

Next time if a big update is on line, i will skip the update for a month. Lesson learned.

Pin a working kernel?:

Saved my day. I tried another boot-tool command i do not remember which told me, the given kernel did not exist. pinning worked.

Code: 
# proxmox-boot-tool kernel list
Manually selected kernels:
None.

Automatically selected kernels:
6.2.16-19-pve
6.5.11-6-pve


# proxmox-boot-tool kernel pin 6.2.16-19-pve
Set kernel '6.2.16-19-pve' in /etc/kernel/proxmox-boot-pin.
Refresh the actual boot ESPs now? [yN] y

Dell PowerEdge R240, dual port BCM5720.
Kernel 6.2.16 boots ok
Kernel 6.5.11-7 (or also 6.5.11-6) hangs at boot.
Last message on the screen is "EFI stub: Loaded initrd from command line option"

I've updated:
BIOS from 2.10.1 to 2.15.1
Broadcom NetXtreme from FFV22.00.6 bc 5720-v1.39 to FFV22.61.8
but still 6.5.11-x does not boot

Kernel 6.2.16-20 no problems...
 
Just to toss some additional data in this thread, I did a fresh install of Proxmox VE 8.1 from ISO on a Dell R740, and had no issues during the install, nor after applying all updates.

I'm in the process of testing out Proxmox in a libvirt / kvm instance. I didn't see anyone specifically calling this setup out, but I had to add `simplefb` to the initramfs modules as mentioned earlier to get a working display.

I don't see a bug at https://bugzilla.proxmox.com/buglist.cgi?quicksearch=simplefb. Is there somewhere better to subscribe to know when it's fixed?

It was fixed in current 6.5.11-7 (or maybe 6.5.11-6) as far as i know.
If you install 8.1 from ISO, you have to update kernel first, because ISO is shipped with 6.5.11-4. You could install 8.0 and update directly to kernel 6.5.11-7.
