Since under some heavy computing environment(dgemm test), it takes
the asic over 10+ seconds to finish the dispatched single job
which will trigger the timeout. It's quite confusing although it
does not seem to bring any real problems.
As a quick workround, we choose to disable timeout when GPU reset
is disabled.
NAK, I enabled those warning intentionally even when the GPU recovery is
disabled to have a hint in the logs what goes wrong.
Please only increase the timeout for the compute queue and/or add a
separate timeout for them.
Regards,
Christian.
