On the other hand my monitors do not seem to have the highest quality. Occassionally the resolution is wrongly detected or DP signal is lost. I am not sure why, I suspect there is some interference between the two DP cables. But this is a problem for as long as I have these two monitors, the NULL-ptr deref only happens with v5.18.

Gentle ping. This is a 5.18 regression and I also see it with 5.18-rc6. Please let me know if you need anything else to debug.

So it's at least not the iommu changes causing it :) Please let me know if I can be of any help debugging this further. Thanks, Joerg

[BUG] Warning and NULL-ptr dereference in amdgpu driver with 5.18
Hi, since recently I started to experience warnings and NULL-ptr dereferences in the amdgpu driver with kernel 5.18-rc5+. Earlier 5.18-based kernels might be affected as well, but I havn't seen this with 5.17. The kernel was built from the iommu-next branch, based on 5.18-rc5.
