Hi,
Is the linux-btrfs list interested in receiving bug reports relating to
btrfs?
If so, the following error occurred on a server of mine when copying a
large amount of data to a linear md-RAID formatted as btrfs. The data
transfer hung, and any attempt to kill or strace the copy process hung
as well until the system was rebooted.

kernel 3.0.0 is positively ancient in btrfs terms. I defer to others on what kernel should be used at the present time for an Ubuntu server, but I know they have much newer kernels than 3.0.0 available.
