Keith,
I noticed that during page faults, the OOPS handler is not getting
called when the kernel crashes in
filp_open() -- the notifier chain does not return for some reason. I
also noticed that when this happens, if you the section in
/arch/i386/kernel/traps.c in function die() prior to the busting of
spinlocks, it will work (sortof work). To reproduce this error, call
filp_open with a text string complied in the kernel. I can reproduce on
2.6.10 and 2.6.11 Fedora Kernels. Also noticed that when Kprobes is
enabled, the debugger page faults during a page fault exeception.
Seems related to the notifier chain.
If you fixed this already, disregard this notice.
Jeff
