Comment 1 Martin Peres 2019-04-08 09:54:46 UTC
The failure actually happened at the end of igt@gem_exec_suspend@basic-s3.

I did not file the bug straight to kernel.org, because there is a chance this is a GEM-induced corruption.
Comment 2 CI Bug Log 2019-04-08 09:58:27 UTC
The CI Bug Log issue associated to this bug has been updated.

### New filters associated

* BSW: igt@runner@aborted - fail - Previous test: gem_exec_suspend (basic-s[34].*), Kernel badly tainted (0x60)
  - https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_5886/fi-bsw-kefka/igt@runner@aborted.html
Comment 3 Chris Wilson 2019-04-08 10:25:47 UTC
I would say this looks pretty clear cut as a use-after-free of the skb.
