See http://bugzilla.kernel.org/show_bug.cgi?id=13819#c4 and while there was some confusion about exactly which commit caused it - probably because the irq thing obviously depends on timing - Reinette had a list of three commits that he used to be able to revert to get things going: drm/i915: Don't update display FIFO watermark on IGDNG drm/i915: add FIFO watermark support drm/i915: enable error detection & state collection So Andrew assigned it to DRI, and Rafael has had both Eric and Ma Ling on the cc for his regression reports because of the bisection. And that has been going on for a long time, I just checked: Date: Sun, 26 Jul 2009 22:28:26 +0200 (CEST) From: Rafael J. Wysocki <rjw@xxxxxxx> To: Linux Kernel Mailing List <linux-kernel@xxxxxxxxxxxxxxx> Cc: Kernel Testers List <kernel-testers@xxxxxxxxxxxxxxx>, Eric Anholt <eric@xxxxxxxxxx>, "ling.ma@xxxxxxxxx" <ling.ma@xxxxxxxxx>, Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx>, Ma Ling <ling.ma@xxxxxxxxx>, Reinette Chatre <reinette.chatre@xxxxxxxxx> Subject: [Bug #13819] system freeze when switching to console If you didn't see it, then that means that we have screw-ups with the bugzilla thing. You're actually listed as a "Reviewed-by" on the commit that the fixed-up bisection blamed - And I get the feeling that Rafael's bugzilla "bugme" scripts may only pick up "Signed-off-by:" lines. The point is: this bug has been in bisected in bugzilla for a month and a half, and had at least two Intel DRI people cc'd on the weekly reminder reports, along with being Assigned To: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx 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=13809 http://bugzilla.kernel.org/show_bug.cgi?id=13740 http://bugzilla.kernel.org/show_bug.cgi?id=13733 http://bugzilla.kernel.org/show_bug.cgi?id=13645 but they aren't bisected and it's not nearly as clear what is going on there. The last one in particular I don't know if it even happens any more and the first one seems to be fixed in -rc5, or at least the reporter couldn't reproduce it any more..
