Mironenkov: Your freeze is different from Arie's; Arie's failure looks SATA related and only then does he see RCU messages, your failure complaining of RCU stalls without any apparent cause. Mironenkov: Please file a separate bug, and state the rcu message in the title.
Arie: Can you please run: apport-collect 855684 to collect logs for this bug, it'll include information about your hardware. Please also use the disk utility on the install CD or smartctl -a to do a smart check of your drives; that error looks like a timeout of some form (not necessarily a bad/failing drive).
