Subject: server reboot recovery is broken with 3.1 (3.2?) with nfsv41 clients

Dear nfs hackers,

it looks like with kernel 3.1 client cant recover from server reboots.
The nfs mount hangs and there are no packages sent from a client to the server.
This was IO with pnfs.

Regards,
Tigran.

RHEL6.2 has the same issue. I just rebooted server (mds + ds) during read.

Kernel thread dump attached.
