sata_mv: module reloading doesn't work

Hello,

I'm testing the sata_mv driver to see whether reloading (rmmod 
- insmod) works, and it seems something is broken there. The
first insmod goes okay - however all the insmods that follow
emit error=0x01 { AddrMarkNotFound } and status=0x50 { DriveReady 
SeekComplete } from all the drives.

I've enabled DPRINTK and fixed a crash involved with register
dumping (posted in my previous mail).

I hope these messages are sufficient, I can provide more 
information if needed.
