After rebooting, PVE completely stops working after some seconds when booted on the new kernel 5.4.44 - even on the console.
No panic, no nothing. Just frozen. Ping stops replying, too.

When booting on kernel 5.4.41, the system runs fine. Can I help debug? The mentioned system is our backup and synchronization target, so it's needed but not mission critical...

does the system finish booting up? - do you get a login prompt?
if not (or in any case) - try removing the 'quiet' from the kernel commandline - maybe this helps in identifying where the problem is.

One other option would be to configure remote syslogging via udp - sometimes the relevant syslog message still makes it to the syslog-server


I hope this helps!
 
The system boots up fine, I can even login if I am fast. Both on console or via ssh. But after a while - or maybe when traffic hits it - it just freezes.
I reverted to kernel 5.4.41 for now - there must be some change that triggers this behaviour, however...
 
I have an HP Proliant ML350 G6, kernel panic after about 1 day. now the 2nd one and because of this, also booted with 5.4.41-1-pve
The last 3 lines output of the console:
Code: 
Kernel panic - not syncing: fatal excepetion in interrupt
Kernel offset [some hex values here]
---[ end Kernel panic - not syncing: Fatal exception in interrupt ]---

The rest of the panic log would probably indicate where the error originated.

Apart from that - make sure to have installed the latest available BIOS/Firmware for the machine - this sometimes helps with issues like these
 
Hi Stoiko,

Unfortunately, HPE only offeres BIOS/Firmware upgrades if you have a support contract for the hardware.
5.4.41 works well, so there must be a change triggering it in 5.4.44. I haven't yet tried 5.4.44.2.

Is there a way to keep the machine from booting 5.4.44 until this problem is solved? So far I have to manually boot that kernel...
