Comment 1 Jon Ewins 2018-12-18 22:34:18 UTC

This is an RSA signature failure after resume from S3.  Interestingly we have already successfully recovered twice before from gem_exec_suspend tests for S3 and S4 before hitting this issue on the kms suspend test.  Can't tell from the log if this test is consistently failing or this is an intermittent issue.
This might be related to the WaEnableGuCBootHashCheckNotSet issue and that is being checked.

Comment 2 Jon Ewins 2019-02-15 23:58:33 UTC

Possibly due to an intermittent Gen9 guc reload issue that can requires retry workaround and that will be tested.  Otherwise, further investigation will be deferred until after upcoming update to guc version.

Last seen drmtip_193 (1 month, 2 weeks / 976 runs ago).
Dropping the priority to high.

Comment 4 Lakshmi 2019-04-02 07:51:21 UTC

Comments from Fosha:
Patch to do GuC load retry sent to upstream mailing list, reviewed, and merged:
https://patchwork.freedesktop.org/patch/295098/?series=58758&rev=2

@Fosha, Can we resolve this bug? or this issue requires more patches to be merged?

    drm/i915/guc: Retry GuC load for all load failures
    
    Currently we only retry to load GuC firmware if the load fails due to
    timeout. On Gen9 GuC loading may fail for different reasons, not just
    hang/timeout. Direction from the GuC team is to retry for all cases of
    GuC load failure on Gen9, not just for timeout.
