cluster reboots sometimes hang (2)

Upstream bug:


Sometimes, when a cluster machine decides it wants to reboot as a user is logging out, it fails to actually reboot, and ends up not at the Ubuntu splash screen, but at the text console with a bunch of things like:

INFO: task [task]:NN blocked for more than 120 seconds
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message

where [task] is things like fsnotify_mark, dbus-daemon, gdm-binar, polkitd, and N is perhaps the corresponding pid?

It is possible to soft-reboot machines in this state, though I don't remember whether ctrl-alt-del works or sysrq-b was needed.

I saw this on a machine that was otherwise in the state of #1052. I think this is normal behavior, in that Plymouth knows to show you the text console when certain horrible things happen?
