I had been unsuccesful to find a reliable way to trigger the freeze 
without mailman. So I created a backup mailman directory by which I can 
test the system. The following has been verified so far:

- Removed commit 17968b0fe87829edff1af7fa9ffbbc92540159fb (Remove 
  splice_read file op for jdata files) and commit
  4787e11dc7831f42228b89ba7726fd6f6901a1e3 (gfs-kmod: workaround for 
  potential deadlock. Prefault user pages), the system freezes.
- Removed commit 5e83cdb08b423478a0b6cc8f6de396ab8328d47a (gfs-kernel: Bug 
  466645 - reproduceable gfs (dlm) hanger with simple stresstest),
  the system freezes.

(Please note, the volumes are mounted with noatime).

If you have any idea what to do next, please write it.

Best regards,   
Jozsef
