Hi, after lots of NFS related troubles, 2.6.32 seems to finally to get to usable state for me. since 2.6.32.9-rc1, it works much better, but we're still getting occasional hangups, and following traces: [109921.032043] INFO: task jbd2/dm-7-8:4338 blocked for more than 120 seconds.

Seems to me that it's either ext4, or jbd2 related. Any opinions somebody? thanks a lot in advance br nik -- ------------------------------------- Ing.
