Message-ID: <20101117032721.GA8630@redhat.com> Mail-Followup-To: Dave Jones , Linux Kernel , Linus Torvalds , Len Brown MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.5.21 (2010-09-15) Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org 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. git bisect start # bad: [c6ea21e35bf3691cad59647c771e6606067f627d] Merge git://git.kernel.org/pub/scm/linux/kernel/git/sfrench/cifs-2.6 git bisect bad c6ea21e35bf3691cad59647c771e6606067f627d # good: [899611ee7d373e5eeda08e9a8632684e1ebbbf00] Linux 2.6.36-rc6 git bisect good 899611ee7d373e5eeda08e9a8632684e1ebbbf00 # bad: [35ec42167bb5f13db93f1e8c13298eb564f95142] Merge branch 'idle-release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-idle-2.6 git bisect bad 35ec42167bb5f13db93f1e8c13298eb564f95142 # bad: [64aab720bdf8771214a7c88872bd8e3194c2d279] i7core_edac: fix panic in udimm sysfs attributes registration git bisect bad 64aab720bdf8771214a7c88872bd8e3194c2d279 # bad: [77f890223338c890fc33972673d2bd3a53061570] Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/djbw/async_tx git bisect bad 77f890223338c890fc33972673d2bd3a53061570 # bad: [9d457c60ba783c709c750b851d07f0ac8af78ce9] Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6 git bisect bad 9d457c60ba783c709c750b851d07f0ac8af78ce9 # bad: [90182317a9e383474613aa60e9d61d57bdf17c3e] mfd: Fix max8925 irq control bit incorrect setting git bisect bad 90182317a9e383474613aa60e9d61d57bdf17c3e # bad: [c9d66d3515bbb0ad8062721487de7ade02d2b936] mfd: Ignore non-GPIO IRQs when setting wm831x IRQ types git bisect bad c9d66d3515bbb0ad8062721487de7ade02d2b936 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 ? Dave
