Hi,

I've upgraded (dist-upgrade) to PVE 8.2.4 today that comes with kernel 6.8.8-2-pve. After a reboot that I always perform after PVE dist-upgrade, PVE didn't come back up. I hooked it up to my TV (HDMI) and noticed that the only messages visible were:

Code: 
Booting Proxmox VE GNU/Linux
Loading Linux 6.8.8-2-pve ...
Loading initial ramdisk ...

Found volume group "pve" using metadata type lvm 32 logical volune(s) in volume group "pve" now active
/dev/mapper/pue-root: recovering journal
/dev/mapper/pue-root: clean, 112422/3932160 files, 8756405/15728640

after which the screen turned black. Not a good sign. I booted the previous kernel (6.5.13-5-pve) via advanced boot options and pinned that kernel now using proxmox-boot-tool kernel pin 6.5.13-5-pve. Now the system is functional again, but may become unstable again in a next dist-upgrade.

I exported the logs using journalctl and noticed the following kernel panics while booting the 6.8.8-2-pve kernel:

I've attached a boot log of both 6.8.8-2-pve (contains mulitple kernel panics/traces) and 6.5.13-5-pve (successful boot).

My system boots up with the following modules added to /etc/modules

Code: 
# Modules required for PCI passthrough
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd

# Modules required for Intel GVT
kvmgt
exngt
vfio-mdev

Any idea what the issue might be, or how I can further debug this?

Thanks in advance!

It's good to report kernel bugs and crashes here in the forum, so that others may find it, but according to my experience, to get anywhere I would suggest you open a bug report in the Proxmox bug tracker: https://bugzilla.proxmox.com/ using the Kernel category.

If you would feel comfortable with communicating directly with the kernel developers, write a bug report to the Linux Kernel mailing list. However this might require you to build and test a custom kernel, and most likely to also do a "git bisect" to find out which code change (git commit) exactly caused this bug. This might not be manageable for everyone.

Also, mainline kernel 6.8.x is EOL with 6.8.12 and not supported anymore by the stable maintainers. However if you could demonstrate that this bug reproduces also on a still supported release like 6.9.7, the kernel devs will care and try to fix the bug; and this patch could then be picked up and eventually, if necessary, backported by Proxmox.

proxmox use the ubuntu lts kernel 6.8, so ubuntu do the job to maintain it for the next 3 years.

Yes, I know. But will they care if a Proxmox user reports a bug in the PVE kernel? Won't they say that the Proxmox kernel team should look into the issue? It's always best, I think, to get a bug fixed by the kernel developers in the highest stable release where it reproduces, and then the patch can trickle down... The reason I think that is, that I don't know how, or whether at all, the Ubuntu kernel team and the Proxmox kernel team cooperate when it comes to investigating and fixing issues.
