After updating kernel in ubuntu 14.04 I found this again. But this time with kernel panic.

And repeates... This makes worse because using ceph, what it means it cannot connect to the net and cannot use the disk where kernel wants to save the coredump, so the ovswitchd process never ends, so I cannot restart it to recover the system. So I have to reboot. Nasty.
