Here's all the details. Please tell if there is anything more I can
do with it. I simply don't know how to find "what line number in the
code"
or which variable maps to what register. But I have done programming
before and can follow instructions. Note that the .o files for this
build isn't around - I have patched the source tree after
booting but before this happened.
The first part probably scrolled off the screen, here is what I got:
EIP: 0060:[<c0119238>] Not tainted
EFLAGS: 00010086
EIP is at wake_up_forked_process+0xb8/0x18c
eax: 5a5a5a5a ebx: c151da80 ecx: 0159f48d edx: 00000000
esi: c0469d00 edi: 51eb851f ebp: dfdd5f18 esp: dfdd5f08

I'll run a test - later.
