This looks like you oopsed in cache_alloc_refill, and then after that the watchdog kicked in, and spewed traces, scrolling the backtrace for the actual oops off the screen. Might be worth trying to reproduce it with CONFIG_LOCKUP_DETECTOR disabled. We frequently see this sort of thing reported in Fedora. It would be nice if we had a means of either reading scrollback when we lockup, or buffering the output so we pause between dumping traces. Dave
