M-Systems SATA FFD fails IDENTIFY cmd

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.

Two other controllers were tested on the x86 machine and they both
worked as expected:

Silicon Image, Inc. Adaptec AAR-1210SA SATA HostRAID Controller (rev 02)
Promise Technology, Inc. PDC20575 (SATAII150 TX2plus) (rev 02)

Is this likely a problem with the M-Systems drive or a libata/driver problem?
