Message-Id: <200809281724.16408.shawn.starr@rogers.com> Date: Sun, 28 Sep 2008 17:24:14 -0400 From: Shawn Starr <shawn.starr@...ers.com> To: linux-kernel@...r.kernel.org Subject: Re: [2.6.27-rc7-git1] (Fedora) - ACPI instabilities and IRQs being disabled On Saturday 27 September 2008 18:40:24 Shawn Starr wrote: I believe http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=de85422b94ddb23c021126815ea49414047c13dc is causing this regression. Can someone confirm this to be the case? It certainly looks suspicious given the handler lines showing this exact sort of code path...
