xfs deadlock in stable kernel 3.0.4

[Stefan Priebe <s.priebe@xxxxxxxxxxxx>]

Hello List,

on some of our heavy loaded servers using xfs we're seeing a deadlock where 
reading/writing to the xfs filesystem suddenly stops working.

Here you can find sysrq w triggered log messages of the locked processes.
