Hi,
I've got a few M-Systems SATA FFD 2.5" solid state disks that behave
strangely with some drivers.
When probing the disks on an Asus P5P800-MX motherboard's onboard SATA
and with an embedded PPC440gx machine with an on-board Intel 31244
(sata_vsc) SATA controller I get the following:

As you can see the INQUIRY command fails after 30 seconds. The x86/ata_piix
machine is running 2.6.19-rc3. The PPC/sata_vsc machine is running
2.6.18.
Can you try 2.6.19-rc3-mm1 and report the result? Thanks.
