    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:


    commit c2fb7916927e989ea424e61ce5fe617e54878827

        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 for the info, Daniel.  I'll go the reverse bisect route.





    Thanks,

    Joe
