--- Comment #9 from Marta Löfstedt <marta.lofstedt at intel.com> ---
Interesting there are no IGT commits between CI_DRM_3611 - CI_DRM_3617, i.e.
same test ordering for all the runs.

maybe it isn't a regression. but some other evil thing happening before.

So, before theigt at debugfs_test@read_all_entries there are:
fail: igt/kms_frontbuffer_tracking/fbcpsr-1p-rte
pass: igt/prime_vgem/fence-wait-render
pass: igt/gem_exec_flush/basic-uc-pro-default
skip: igt/kms_plane_lowres/pipe-f-tiling-none
dmesg-warn: igt/pm_rpm/debugfs-read
pass: igt/kms_3d                                  


igt/pm_rpm/debugfs-read
<7>[   98.926697] [drm:sandybridge_pcode_read [i915]] warning: pcode (read from
mbox 5) mailbox access failed for i915_drpc_info [i915]: -6

- 6 =>
        case GEN6_PCODE_ILLEGAL_CMD:
                return -ENXIO;
