{- VEGA M: igt@amdgpu_amd_basic@userptr - dmesg-warn - general protection fault: 0000 [#1] PREEMPT SMP PTI -}
{+ VEGA M: igt@amdgpu_amd_basic@(semaphore|userptr) - dmesg-warn - general protection fault: 0000 [#1] PREEMPT SMP PTI +}

 No new failures caught with the new filter
Comment 3 harish.chegondi 2019-11-08 19:55:35 UTC 
There are two issues associated with this bug:

https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_7252/fi-kbl-8809g/igt@amdgpu_amd_basic@semaphore.html

https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_7252/fi-kbl-8809g/igt@amdgpu_amd_basic@userptr.html

While the CI buglog indicates that the last failure happened almost 5 months ago and there have been 1517 covered runs since the last failure, the userptr test (link mentioned above) has been failing consistently but with a different failure signature (probably the reason why the issue filter is not catching it?)

The userptr test has been failing recently with "No such device" error with the signature below.

(amd_basic:3914) CRITICAL: Test assertion failure function amdgpu_userptr_test, file ../tests/amdgpu/amd_basic.c:1335:
(amd_basic:3914) CRITICAL: Failed assertion: r == 0
(amd_basic:3914) CRITICAL: Last errno: 19, No such device
(amd_basic:3914) CRITICAL: error: -19 != 0
(amd_basic:3914) igt_core-INFO: Stack trace:
(amd_basic:3914) igt_core-INFO:   #0 ../lib/igt_core.c:1716 __igt_fail_assert()
(amd_basic:3914) igt_core-INFO:   #1 ../tests/amdgpu/amd_basic.c:1324 __real_main1383()
(amd_basic:3914) igt_core-INFO:   #2 [main+0x30]

On the other hand the semaphore test has been consistently passing in the recent runs.
