Hi Daniel,

A bug was opened against the Ubuntu kernel[0].  After a kernel bisect, it was found the following was the first bad commit:

    Merge tag 'v3.7-rc2' into drm-intel-next-queued



The regression was introduced as of v3.8-rc1.  However, further testing also shows this bug is now fixed in v3.9-rc4.

I see that you are the author of this patch, so I wanted see if I can get your feedback.  Do you happen to have an idea what may have fixed this in v3.9-rc4, so we can send a request to stable, if not already done?  Otherwise, I can perform a reverse bisect to see which commit fixed this.

So apparently it's an oops somewhere in the nouveau setup code, which bisected to a backmerge which has _only_ conflicts in drm/i915 driver code.

I have no idea what blew up here, sorry.

Thanks,

Joe
