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.
