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.
