Comment 1 Martin Peres 2018-10-29 15:54:55 UTC
Setting the bug to HIGH because it is hit in BAT (which warrants HIGHEST), but the GUC is disabled by default (which warrants MEDIUM).
Comment 2 Jon Ewins 2019-02-15 23:58:20 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.

Robert/Jon, Any updates here?
Comment 4 Jon Ewins 2019-03-29 15:46:00 UTC
Code has been implemented for the retry mechanism and is to be tested against cases of spurious load failure.

    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.
