Hi,
The SATA interface can be switched between AHCI and legacy modes as usual:
00:1f.2 SATA controller: Intel Corporation NM10/ICH7 Family SATA
Controller [AHCI mode] (rev 02)
The device attached to the SATA controller is always a CF card via a
SiI3811 Serial ATA to Parallel ATA Device Bridge based converter board.
Can you please attach a normal sata disk and try again with the
controller set to AHCI mode? I suspect it may be the SiI3811 bridge that
caused this command.
I have finally got around to testing a different beast, a Zotax ZBOX with
mostly the same motherboard components that the previously mentioned
embedded PC had. It turned out that this embedded PC (a POS machine)
doesn't have regular SATA connectors but a special one to connect only
this SATA-EIDE converter card with the SiI3811 chip.
Anyway, using the Zotac box, both a shiny new Samsung 840 SSD
and a CF card using a different IDE bridge chip (Sunplus SATALink SPIF223A)
can suspend to RAM using AHCI mode.
Your suspicion turned out to be correct.
Best regards,
Zoltán Böszörményi
