Subject2.6.12-rc2: random oops on nmi_watchdog=1
DateTue, 5 Apr 2005 15:13:10 +0900
With nmi_watchdog=1, I got random Oopses (Unable to handle kernel
paging request, not by the NMI oopser) from many processes.
It is not happend with -rc1.

The following change fixes this problem. but I'm not familiar with
these area.  If anyone wants more information, let me know.
