RE: 2.6.23.1 - sata_mv (7042) hang with large file operations

I have gotten it to boot from those hard-drives and it
has the same behavior:

Copying a large file to the same partition (>150MEG)
causes the system to hang (no I/O - no input/output -
nothing - complete freeze - like a primary resource
is locked up or interrupts got completely & totally
turned off in an ISR and its pending for something?

Only way to get out of this is to power-cycle the box!

MMmm.. I'd like to see that again without the rootfs-on-NFS.

What exactly do you mean when you say "it just hangs" ?
Everything (dead system)?
