3.11 and 3.12rc continual hard lock ups

2013-10-23 Thread Sean Clarke
Hi, I have an Intel Core i7 based fileserver with 18TB BTRFS in a 6x 3TB RAID 1+0 configuration. The system was working fine running Ubuntu 13.04 (kernel 3.11.0-12-generic). The system was upgraded to Ubuntu 13.10 (kernel 3.11) and began to lock up daily, sometimes every couple of hours.
