Are you sure that the System.map and the kernel that you are running
match??? in the calltrace, __find_get_page didn't appear, and you put
that it is the place where you are having problems. Could you check
if you have also a line with BUG(): <some text here> in your logs just
before that Oops?

Later, Juan.
