Hi,

my homelab Proxmox server crashed a few hours after updating to 5.13.19-2-pve kernel, i am unsure if 5.11 was running before but there weren't any stability issues with this system until now. Any help appreciated.

Best regards,
Malte

I have a similar issue - once I perform a proxmox backup, I get a similar kernel crash. After this update too..
 
That's interesting because i have two similar Gigabyte BLCE-4105 barebones and i was moving everything to the second system (to do some hardware checks on the first) after the crash on friday. While doing that some of my backups seemed to be corrupted:

So i ran fsck inside the VMs but the filesystem had no issues. Did another backup and i was finally able to import them. Currently running Kernel 5.11.22-7-pve, no problems so far.

What's your hardware configuration?
