[qubes-users] Qubes 4.0 dom0 kernel problems (boot loop, panic, freeze)

I have several dom0 kernels installed (on a Dell XPS13) but only one works fine:

5.11.8-1.fc25.qubes.x86_64 → boot loop
5.11.4-1.fc25.qubes.x86_64 → boot loop
5.10.8-1.qubes.x86_64 → kernel panic
5.4.107-1.fc25.qubes.x86_64 → does not wake up after suspend
5.4.98-1.fc25.qubes.x86_64 → does not wake up after suspend
5.4.88-1.qubes.x86_64 → OK so far.

Updating the kernel would remove the working one…

Any idea what could be wrong? I use qubes-os since version 2 and never had that problem…

Hi Peter,

Fedora, by default, keeps only the 3 last kernel versions. So before updating the kernel, uninstall the most unwanted version. Or change the `installonly_limit` (see Installing older kernels)

About the kernels which didn't work, see the numerous related issues about >= 5.4 kernels, some examples:
