Here comes another trace log, with your info2.patch applied.

Something must have changed since the last test, as it took pretty long this
time to reproduce the crash. Could that have been caused by

However, the latest trace you find attached below is not much different to =
the
last one, xzcat /tmp/gpu_debug5.txt.xz  | grep '^\[' will tell you:

-------------------------------------------

So even without GPU reset, still no "waves". And the error messag=
e also does
not state any VM fault address.
