Lin Manfu (linmanfu) wrote (last edit ): Re: Kernel update 5.15.0-112 might cause severe problems with specific AMD GPUs

Attached is an annotated copy of my system log with the relevant update from 107 to 112, the failed boots with 112, a successful boot with the last good kernel 107, and a boot with 112 using the workaround. Search for BOOT in capital letters to find the start of each boot. I hope this might be helpful.

I am no expert, but perhaps these lines might be relevant, as they only seem to occur on the failed boots with 112:
