Description Joonas Lahtinen 2015-12-08 16:09:54 UTC
When running the BAT test basic-rte@pm_rpm, the following problem appeared. Could QA confirm this by running the test in a loop and observing the results. After first failure, further test executions fail immediately due to runtime resume getting disabled.

[ 1585.658601] pm_rpm: executing
[ 1585.705635] pm_rpm: starting subtest basic-rte
[ 1587.610621] pm_rpm: exiting, ret=0
[ 1587.645533] pm_rpm: executing
[ 1587.693028] pm_rpm: starting subtest basic-rte
[ 1589.606685] pm_rpm: exiting, ret=0
[ 1589.642290] pm_rpm: executing
[ 1589.689337] pm_rpm: starting subtest basic-rte
[ 1591.465623] [drm:vlv_force_gfx_clock [i915]] *ERROR* timeout waiting for GFX clock force-on (00000004)
[ 1591.465781] [drm:intel_runtime_resume [i915]] *ERROR* Runtime resume failed, disabling it (-110)
[ 1591.628487] pm_rpm: exiting, ret=99
[ 1591.661458] pm_rpm: executing
[ 1591.708479] pm_rpm: starting subtest basic-rte
[ 1591.846259] pm_rpm: exiting, ret=99
[ 1592.024886] pm_rpm: executing
[ 1592.071936] pm_rpm: starting subtest basic-rte
[ 1592.209075] pm_rpm: exiting, ret=99

This was after a long session of debuggin other problem, so not attaching the full kernel log.

Comment 2 Kimmo Nikkanen 2016-05-09 18:22:48 UTC
QA, ping?
Comment 3 yann 2016-05-09 18:34:06 UTC
Ricardo, can you organize a re-test today and publish the result?
thanks

With the following configuration we are not able to reproduce the issue:
No matter this, i'm executing the following stress cycles on the same test.

1 iteration=Success
10 iterations=Success
100 iterations=Success

Passing through the following steps:

pm_rpm: executing
pm_rpm: starting subtest basic-rte
pm_rpm: exiting, ret=0


Attaching Dmesg log for further reference.
Please let me know if there is an special condition to reproduce the issue.
