Bug#734370: btrfs lockup with 3.12 RT kernel

[Samuel Orr <uraharakisuke153@gmail.com>]

Hi,

I can confirm this problem as well. It shows up most often when I try to do anything using aptitude (even hitting "tab" to list packages) causes my system to hard lock. I can still interact with running programs but anything that requires disk i/o will not happen, including running sync.
