The problem comes ONLY when I am doing large file operations (e.g.: just copying a file) to/from the SATA drives behind the subject line 7042....it just hangs after about 10-15 seconds into the copy...<snip other drivel>
How large a file causes the hang - you ask - well, somewhere between 100Meg & 500Meg...

Linux-2.6.23.1

2x250GIG Western Digital - 3 partitions (largest (/dev/sda3

7042 PEX on a MPC8548 Board
::: -- exact command line sequence to cause the failure
NFS mount root file system (I am currently rebuild to take away
the NFS file system dependency) - /dev/sda3 is drive in question...
