No, that seems to be a separate issue; I can still reproduce it with the
huge page related changes reverted. Unfortunately, it doesn't seem to
happen reliably on every piglit run.
Can you enable KASAN in your kernel, and please look up at which line
number amdgpu_vm_bo_invalidate+0x88 is.
Even before your changes this morning, there's another hang which
doesn't happen every time, without any corresponding dmesg output.
Lots of "fun" in amd-staging-drm-next...
Yeah, way to much stuff on my TODO list and not enough time/resources
for extensive testing :(
Thanks for the reports,
Christian.
