Hi,

I just posted this in the Framework 16 / Linux section (no idea how to crosspost this to 13 and Desktop, because it applies to these aswell):

Attn: critical bugs in amdgpu driver included with kernel 6.18.x / 6.19.x!

While doing some research for my upcoming Linux installation on my Framework 16 which arrives this week, I noticed the following kernel issue mentioned on Gentoo’s bug tracker: It mentions that after heavy GPU workloads (in this case training on PyTorch) on the Radeon 890M (aka gfx1150, aka the internal GPU of Strix Point / HX370) the system becomes unstable. Later in the thread the OP mentions that he has pinpointed the problem to broken CWSR (Compute Wavefront Save/Restore) which causes t…

TL;DR: Some changes in the amdgpu driver included with kernel 6.18 seem to be broken to the point it leads to crashes and reboots on newer (RDNA 3/4) AMD GPUs. Also just noted that it very likely applies to older kernels with a backported driver aswell.
