On Tuesday this week, I received a Kernel update from 3.19.0-20 to 3.19.0-21 on my laptop (Latitude E6520). At reboot I had kernel panics, so I picked 3.19.0-20 from the boot menu and all was well for the rest of the day. The day after (i.e. yesterday), kernel 3.19.0-21 booted without problem, and everything was running OK except the Docker daemon. Rebooting with kernel 3.19.0-20 fixes it. Anyone has an idea how to possibly unblock it? Otherwise I'll set 3.19.0-20 as my default kernel until the next update.
UPDATE: Docker 1.7 doesn't solve it. Log is different though (see below).
With kernel 3.19.0-21 and Docker 1.7.0:
