Hi ,

it seems that with the latest release I have some problems with oracle Virtual Box.

The kernel fails to load virtual-host-dkms

I don't know if this is related, but 5.19.14.lqx1-1 also fails to load the zenpower module. I noticed because I lost CPU temp/power monitoring after upgrading to this new kernel.

$ sudo dmesg |grep zenpower

[ 6.109668] zenpower: loading out-of-tree module taints kernel.
[ 6.109690] zenpower: module verification failed: signature and/or required key missing - tainting kernel
[ 6.109834] failed to validate module [zenpower] BTF: -22

Worked fine on previous lqx kernels.

...aaaand of course I just tried to launch one of my VMs and I also have an issue with the virtualbox modules - which is a bit more relevant to the thread. :)

Revert to 5.19.13-1 and everything works as expected.

Hmm, the 5.19.14 release was a regular stable upstream update. Is DKMS failing to build modules in your apt-get output?

EDIT: 5.19.14/5.19-17 and 5.19.12/5.19-16 have debug info added
:: Code ::
linux-liquorix (5.19-17) unstable; urgency=medium

  * merge 5.19.14
  * update version to 5.19.0-14.1

linux-liquorix (5.19-16) unstable; urgency=medium

  * add dependency on pahole / dwarves for debug info
  * update version to 5.19.0-12.3

However, there is no 5.19.13 version, that was skipped since upstream changed so fast I never had a chance to update to it.

Ok, latest version just release should fix this issue. The problem was that enabling debug info changed the way modules are signed, and the signature of the modules would get stripped off causing everything to fail validation.

Even though signature validation is not required, it appears you guys are still affected. Try out the latest kernel and let me know if that fixes it.

Confirmed on another system this resolves build errors with DKMS, marking as resolved.
