Thanks for the detective work!

<linux-a...@vger.kernel.org>. Please cc me or this bug log when doing so so
we can track it.
By running
apt-get install git
git clone \
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
cd linux
git log v3.0..v3.1 -- drivers/acpi/pci_irq.c
I see that you will want to mention the patch d7f6169a0d32 ("ACPI: fix
CONFIG_X86_REROUTE_FOR_BROKEN_BOOT_IRQS") when doing so and cc
Stefan Assmann <sassm...@kpanic.de>, Steven Rostedt
<rost...@goodmis.org>, and Len Brown <len.br...@intel.com>.
By the way, does backing out that patch (for example by running "git
revert d7f6169a" followed by "make localmodconfig", "make deb-pkg",
and installing the resulting .deb) fix it for you?
Thanks and hope that helps,
Jonathan
