After last update: Cannot open iommu_group: No such file or directory

[KlausR]

I tried kernel 6.11, but the problem persists.

After doing this 'proxmox-boot-tool kernel pin 6.8.12-2-pve`. Is there anything to do when a new version comes out?
Do I need to remove or modify this line when the new kernel is fixed or upgraded? If so I am not sure where( What file) or how to remove this to get back to the newer kernel.
Appreciate any step by step instructions.
Thanks

Hi,
sounds like this might be the fallout from the fix of another issue:

sent a patch for reverting the issue that @fiona found as well - after a few tests.

`proxmox-boot-tool kernel pin 6.8.12-3-pve` works to re-enable.
Is it safe to update the rest of the packages after rolling back and pinning the older kernel?

yes seems like it
