Some diagnostic output may be missing because it was scrolled off screen by a subsequent oops, which I have assumed was induced by this crash and not, therefore, copied down. Also, I skipped writing down the modules linked because it's a long list, but there are no out-of-tree modules of any kind and the kernel was not tainted (until after this crash). last sysfs file: /sys/devices/virtual/bdi/8:32/uevent Modules linked in ...

Consequently, recreating the crash might not be possible. Nevertheless, let me know if there's any way I can help to fix this. Chris -- The more I see, the more I know.
