--- Comment #4 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Was there anything before the tlb flush timeout error? Unfortunately I have no
clue why those timeouts happen... basically it's an indication that the GPU is
"done". You could disable GL stuff for chromium, either launching it with
LIBGL_ALWAYS_SOFTWARE=1 or by disabling stuff in about:flags.

Perhaps the memory comes up in a (slightly) funny state? You could try
reclocking it and see if that improves matters, have a look in
/sys/kernel/debug/dri/0/pstate for the available perf levels, you can echo
those values in to change states.
