Hi,
I noticed a machine to hang after a few days of uptime,
i.e. the USB, networking etc are all gone, but the machine is still up
and displaying the login screen.
I am running
$ uname -a
Linux sd 3.12.5-302.fc20.i686 #1 SMP Tue Dec 17 21:01:18 UTC 2013 i686 i686
i386 GNU/Linux
Today I got these messages:
