Still waiting for test feedback on maxcpus and the patch which has since been merged,

    drm/i915: Serialise updates to GGTT with access through GGTT on Braswell

Comment 10 Rami 2015-11-20 10:46:31 UTC

The patch does not apply.
with maxcpus=0 we can't boot.
I tried with maxcpus=1 and all tests pass

Comment 11 Chris Wilson 2015-11-20 11:01:20 UTC

If your kernel is uptodate (drm-intel-nightly) all you need do is now test with a normal boot as my proposed fix has already been applied.

It is fixed on drm-intel-nightly.
Next GFX stack release will also contain the fix.
So closed.

Presumably you will remember to file a bug report for the current failures in gem_concurrent_blit + braswell?
