Bug Description
Reiserfs seems to have triggered freezes in several applications. They are hard kernel level freezes (the process is blocked in the kernel). This happened while I was away from the machine. Chromium, GNOME Terminal and other basic Unity/Gnome apps were sitting idle. The problem went away once I rebooted the machine. Reiserfs is used only for my /home.
Attached is a kernel log that shows stack traces from the blocked processes. But here is the interesting bit, ubuntuone-syncd and chromium-browser had identical stack traces in the kernel freeze:

Thank you for taking the time to file a bug report on this issue.
However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.
We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.
If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.
Thank you for your help, we really do appreciate it.
