2.6.12-rc1-RT-V0.7.41-15: it_real_fn oops on boot in run_timer_softirq

[Lee Revell <rlrevell@joe-job.com>]

Since 2.6.12-rc1-RT something I get this Oops on boot about 50% of the
time.  It's clearly some kind of race because if I just reboot again it
works.  Seems to happen shortly after ksoftirqd startup (maybe the first
time we hit the timer softirq?).

This is (lazily) hand copied and incomplete, but hopefully is enough
info...

EIP is at it_real_fn+0x2f/0x70
eax 0 ebx df9020f0  ecx 1 edx c0019b49
esi 0 edi "       " ebp dffd5f44 esp  dffd5f34
ds 7b es 7b ss 68 preempt 1
process ksoftirqd/0, pid 2, tid dffd4000, task dffd1110
