Comment 4 for bug 1266305

kernel 3.12.0-1-generic (AMD 64)

Twice today I recognized a freeze.

BUT:

* the system becomes stable again after a while
* ata1 will be reset
* system becomes unstable (eth0 network, wlan still works)

You can see some message, that come from a service, that every minute tries to touch and remove a file, and applies the "sync" command.

See the end of the syslog.txt.
