OK, will send it as soon as I get my hands on it (I'm building a new
kernel at the moment with full debug info). In the meantime, if you
have a copy of fs/proc/array.o handy, have a look at do_task_stat
dissassembly and search for movzbl (%eax), %eax. Regardless of my
kernel config, architecture or whatever, the oops is in that
instruction (clearly a NULL pointer dereference). From some previous
debug build I found out (via objdump -dl) that it's apparently at the
entry point of the get_task_stat inline function.
