Subject: sata_nv - ADMA issues with 2.6.20

I've just upgraded my home server to 2.6.20. It's got an Athlon64 on an ASUS
nForce-4 motherboard running a 32 bit kernel. I've had to fall back to using
sata_nv.adma=0 on the kernel command line. One of the NCQ capable drives
repeatedly produced the following errors. There wasn't much disk IO going on
at the time. It's perfectly happy now with ADMA disabled. Strange thing is the
other identical drive ata8 showed no problems (they're both part of a software
raid1)

Some clues follow.

Cheers
David
