It is jumping to la-la land, apparently from "do_swap_page()". The interesting part there is that do_swap_page() doesn't even follow any suspicious function pointers or anything..
Can you do a
gdb vmlinux
and send me the output of "disassemble do_swap_page", along with a copy of the oops (the latter just because I don't keep archives of linux-kernel, so I don't want to have to search for the oops again).
Oh, and only the first oops tends to be the really interesting one - after the kernel has oopsed once, kernel data structures are quite possibly corrupt, and subsequent oopses are suspect. That do_swap_page one _was_ the first oops, right?
