[Bug 2068738] Re: Kernel update 5.15.0-112 might cause severe problems with specific AMD GPUs

Hi Tino,

It says Fix Released for Ubuntu, aka, the latest Ubuntu release, which
is 24.10 Oracular, as it isn't affected. Maybe I should have marked it
invalid in the first place.

Anyway, once someone tries the test kernel I built yesterday to see if
it fixes the issue, I can go about getting the patch into Jammy's 5.15
kernel.

Thanks,
Matthew
