Subject: Revert a bunch of patches in stable kernels
Date: Mon, 18 Mar 2013 11:05:26 +0100 [thread overview]
Message-ID: <CAKMK7uE9o7CT4Bn1SrPyCa+bGrHmj2-+cpDYP__gUU+BRiGH7A@mail.gmail.com> (raw)
Hi Greg&all,
So a recent stable backport to fix rc6 on ilk (which is disabled by
default and with dubious power savings at best, unlike rc6 on snb and
later) totally blew up all over the place:
https://bugzilla.kernel.org/show_bug.cgi?id=55291
https://lkml.org/lkml/2013/3/14/540
There might be more, I'm still recovering from mail floods due to
traveling last week. I think the right course of action is to revert
the offending patch (plus anything depending upon it) and give up on
rc6 on ilk in 3.8 - too messy. All bug reports confirmed that 3.9-rc
kernels work as expected. Upstream commits to revert:
15239099d7a7a9ecdc1ccb5b187ae4cda5488ff9 drm/i915: enable irqs earlier
when resuming
52d7ecedac3f96fb562cb482c139015372728638 drm/i915: reorder setup
sequence to have irqs for output setup
Cheers, Daniel
