Subject: failure to boot any kernel since 2.6.36rc6-git2.
Date: Tue, 16 Nov 2010 22:27:22 -0500 [thread overview]
Message-ID: <20101117032721.GA8630@redhat.com> (raw)
Every kernel between 2.6.36-rc6 and 2.6.37rc2 fails to boot on my laptop.
The -git's that followed -rc6 had a fairly large (considering rc6) acpi merge,
which I suspected was the cause.
The boot failure manifests by a complete lockup as soon as usb initializes.
I spent the last 6 hours bisecting it, and every bisect point failed to boot
(sometimes in slightly different ways, but always just after usb initializes)
http://codemonkey.org.uk/junk/usb-hang/IMG_0054.JPG and
http://codemonkey.org.uk/junk/usb-hang/IMG_0056.JPG being the more common type,
but http://codemonkey.org.uk/junk/usb-hang/IMG_0055.JPG showed up at one bisect point.
The real kicker is that it eventually pointed at something that can't be relevant,
as it patches a file that I don't even compile in my config.

Before I start going through every one of those acpi commits one by one, does
anything jump out from the screen captures that fingers a specific patch ?
Sidenote: booting with initcall_debug didn't print anything. Did that break ?
