OS: CentOS 5.5 x86_64

I attache /var/log/messages.
The system was working but any access to affected filesystem caused the accessing process to block.
To get it to normal state again a reset was necessary (reboot hung of course).

The filesystem that was exported was stacked as below:
RAID1->LUKS->LVM->Ext3.

I had 2 such issues.

I had similar issue in the past using nfs v4 exports. Bug #612101
