Created attachment 129468 [details] dmesg during On patchwork run Test gem_busy/basic-hang-default Causes flip-flop pass -> DMESG-WARN (fi-hsw-4770r) and on previous run passed fine. Test results: https://intel-gfx-ci.01.org/CI/Patchwork_3763/fi-hsw-4770r/igt@gem_busy@basic-hang-default.html Dmesg (attached)
That's unlikely to be us (directly).
Could not see on HSW-4770R with kernel 15ccc64 and config from https://intel-gfx-ci.01.org/CI/CI_DRM_2243/kernel.config.bz2 32/32 tests pass Fedora 25 System: GIGABYTE M4HM87P-00
Assuming this is more mutex fallout [fixed with pre-v4.11-rc1 merge in tip] until proven otherwise.
Seems one fail now instead of warning https://intel-gfx-ci.01.org/CI/CI_DRM_2272/fi-hsw-4770r/igt@gem_busy@basic-hang-default.html Should we re-open?

The important note there is: Hangcheck active, fires in -127360ms I've yet another patch to try and get more information here, but it is looking like either the timer didn't fire, or the work was never run. The next patch adds a message to try and distinguish those two cases.
