The following commit updated gmc->noretry from 0 to 1 for GC HW IP
9.3.0:
commit 5f3854f1f4e2 ("drm/amdgpu: add more cases to noretry=1")
This causes the device to hang when a page fault occurs, until the
device is rebooted. Instead, revert back to gmc->noretry=0 so the device
is still responsive.
Wait a second. Why does the device hang on a page fault? That shouldn't
happen independent of noretry.
So that strongly sounds like this is just hiding a bug elsewhere.

Christian.
