    Hi,

    -> compiling 2.6.12-rc2-mm1 on amd64 :

    arch/x86_64/kernel/nmi.c:116: error: static declaration of
    'check_nmi_watchdog' follows non-static declaration
    include/asm/apic.h:102: error: previous declaration of
    'check_nmi_watchdog' was here

    I guess the fix is easy enough :)

    -> while I am it, I got a soft lookup on a bi-opteron using
    2.6.12-rc1-mm4 (while stressing reiser4 with rsync so I guess it is
    reiser4's fault ;)
    config at
    http://www-fourier.ujf-grenoble.fr/~mmarcha/config-2.6.12-rc1-mm4.gz

    I also got some "flushing like mad" warning messages from reiser4 (which
    are safe apparently).

    BUG: soft lockup detected on CPU#0!
