This Oops happens under heavy load with
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=7b104bcb8e460e45a1aebe3da9b86aacdb4cab12
head.
Also i run the powertop tool in parallel of the build process.
This is what i could capture with netconsole:
"BUG: unable to handle kernel NULL pointer dereference at virtual address
00000003
printing eip:

*pde = 00000000
Oops: 0000 [#1]

System.map says:
c0136d47 t tick_nohz_handler
c0136e30 t match_entries
c0136e5a t tstats_open
match_entries is part of kernel/time/timer_stats.c
and only used within timer_stats.c
I guess without stack values this is hard to debug...
I cc'ed Ingo Molnar and Thomas Gleixner as they signed of the initial patch for
the timer_stats support:
