At the moment, I have the Sil PM plugged in, and it all behaves nicely.
The previous failure was with the Marvell PM, so I'll hook that up next
and retest with it.

It went bonkers again. This is with 2.6.25.
I'll build 2.6.26-git and try again with that shortly.

Okay, I have today's 2.6.26-rc2-git installed now.
My PCIe notebook has an ExpressCard with this on it:
0d:00.0 Mass storage controller: Silicon Image, Inc. SiI 3132 Serial
ATA Raid II Controller (rev 01)
That's the controller I use with sata_sil24 here.
I have a Marvell 4140 port-multiplier (standalone card),
and have a Seagate 750GB drive (pmp=0) and a Hitachi 500GB drive (pmp=2).
When I simply do "hdparm -t" simultaneously on both drives,
something gets very confused somewhere. Neither drive has any media
errors,
and this exact same test works fine with sata_mv in my other system.
The same test also works fine with both controllers
when using a Silicon Image PM instead of the Marvell.
When I move the second drive to pmp=1 (instead of pmp=2),
then sata_sil24 no longer has problems. Very peculiar.
Here's the log from sata_sil24, ports 0,2, as it fails:
..
And here is the log from sata_sil24, ports 0,1, as it works:
Heh.. detection doesn't work too well either. I have to tell you mv
4140 is my favorite pmp. It just behaved right. Ironically, all later
works were focused on simg 3726/4726's because they didn't behave. I'll
give well-deserved love to my 4140 and get back to you soon.
Thanks.
