Some discussion has been offline. Please test with no guc too.
More importantly, please use the upstream kernel before filing a bug against it.
we are using 4.14 RC2 kernel
drm-tip is on 4.14 RC4 we will update with that kernel. If issue still exists we will reopen this BUG. Please let me know is that ok
(In reply to Pallavi G from comment #5) > we are using 4.14 RC2 kernel The error state shows that you have patches above that, patches that I know affect execution...
