    Subject[bug, 2.6.26-rc4/rc5] sporadic bootup crashes in blk_lookup_devt()/prepare_namespace()

    -tip testing has started triggering a new type of sporadic bootup crash
    a few days ago. Find below a collection of 14 crashes i've managed to
    capture so far, which are all similar to this crash pattern:

    BUG: unable to handle kernel paging request at ffff81003b984fb8
    IP: [<ffffffff803fafd4>] blk_lookup_devt+0x42/0xa0

    Oops: 0000 [1] SMP DEBUG_PAGEALLOC

    Call Trace:

    I have reproduced it on different 32-bit and 64-bit systems as well, so
    it's not a hardware issue and it seems to affect the generic kernel.

    Unfortunately the crashes are very sensitive to kernel layout changes so
    my efforts to bisect this failed. Sometimes repeat bootups do not
    reproduce the bug (making bisection even harder), and they all occured
    with DEBUG_PAGEALLOC kernels which suggests it's a timing sensitive data
    structure lifetime problem.

    The latest crash's config and full serial console capture is:

    http://redhat.com/~mingo/misc/config-Mon_Jun__9_07_52_56_CEST_2008.bad
    http://redhat.com/~mingo/misc/crash-Mon_Jun__9_07_52_56_CEST_2008.log

    i havent had time to look into the bug in detail yet, but it looks
    worrying and i think the bug is in -git too.

    The first git-tagged crash was 2.6.26-rc4-00006-g1419a3b-dirty, which
    corresponds to tip-history-2008-06-04_09.44_Wed-6-g1419a3b, which has
    this upstream -git component:

    | commit 1beee8dc8cf58e3f605bd7b34d7a39939be7d8d2
    | Merge: 9db8ee3... 3446b9d...
    | Author: Linus Torvalds <torvalds@linux-foundation.org>
    | Date: Fri May 30 07:45:20 2008 -0700

    which is v2.6.26-rc4-103-g1beee8d. Given how sporadic this crash is (it
    takes thousands of random kernel bootups to trigger), it could have been
    introduced anytime, but i'm fairly sure it got introduced (or made more
    prominent) in the v2.6.26 cycle - and not necessarily in the -rc3/-rc4
    timeframe. (that's just when -tip testing has managed to cut through the
    many trivial problems that hit early -rc's and got up to full speed and
    full coverage)

    the 14 crashes below are a grep -C 50 context grep from the boot logs.
