I reproduced this bug (kernel panic, total freeze) this morning by doing *two* simultaneous rm -rf commands on folders created by copying /bin /lib /boot /etc /lib64 /root /srv /usr /opt /sbin /var into two backup folders on another ext4 partition.
At least something was damaged in the crash because Skype needed my password after rebooting, but I'm not sure what else might have been affected. The folders I was deleting at the time of the crash were largely intact.

I had netconsole running on another computer, but nothing at all was logged there about the panic, unlike in https:/ /bugs.launchpad .net/ubuntu/ +source/ linux/+ bug/330824/ comments/ 57.
