Reinette actually mailed me offlist about this; we corresponded privately about this issue a month ago; I lost track of it while on vacation (yeah I'm not on the cc lists for the bz or regression updates). Totally my fault. Anyway the bisects look like they might just be lucky; it sounds like this wasn't a KMS related issue at all... > We have other bugs on the regression list that are even older (no, > I'm not proud of them): > > http://bugzilla.kernel.org/show_bug.cgi?id=13740 This one looks gfx related, upstream bug is https://bugs.freedesktop.org/show_bug.cgi?id=23096. The graphics group tracks freedesktop.org bugs on a weekly basis since that's where a vast majority of our bugs our filed (often from OSVs); I'll get the kernel bugzilla stuff included in our future scrubs so we don't miss stuff like this. -- Jesse Barnes, Intel Open Source Technology Center
