(gem_eio:2635) CRITICAL: Failed assertion: elapsed < 250e6
(gem_eio:2635) CRITICAL: Wake up following reset+wedge took 3723.972ms
Subtest reset-stress failed.
Introduced by:
igt/gem_eio: Measure reset delay from thread
We assert that we complete a wedge within 250ms. However, when we use a
thread to delay the wedging until after we start waiting, that thread
itself is delayed longer than our wait timeout. This results in a false
positive error where we fail the test before we even trigger the reset.
Reorder the test so that we only ever measure the delay from triggering
the reset until we wakeup, and assert that is in a timely fashion
(less than 250ms).
