What do the warnings mean? :-)
That your drive does not support set transfer mode/speed command at
all, or that value which kernel tried is not supported by the drive...
I would guess that some contractor wrote firmware for device for PQI
in one day for $100, and before that somebody else designed ATA-SD
bridge for PQI for another $100.
I guess that these two printk()s happen because drive claims to
support pio0,1,2 - so Linux tries pio2, drive refuses, Linux tries
pio1, drive refuses, and finally as pio0 is default, that one gets
used. Which is more or less confirmed by having no '*' sign in front
of any pio - with "real" drives you should see '*' in front of one of
listed dma/pio modes.
You should ask reseller how they can ship drive which does not conform
to any ATA standard...
I took drivers/ide/pci/via82cxxx.c and sprinkled ENTER/EXIT printk's.
http://lxr.linux.no/source/drivers/ide/pci/via82cxxx.c
via82cxxx_tune_drive() and via82cxxx_ide_dma_check() both call
via_set_drive() which calls ide_config_drive_speed().
http://lxr.linux.no/source/drivers/ide/ide-iops.c#L769
if (error)
{
(void) ide_dump_status(drive, "set_drive_speed_status", stat);
printk(KERN_INFO "EXIT %s error\n", __func__);
return error;
}
Does someone know why error is not set to 0?

According to my supplier, herre is the data sheet for the DOMs:
http://www.pqimemory.com/documents/domdata.pdf
PIO mode 2 is mentioned. Even DMA seems to be supported.
Or am I mistaken?
Could there be a bug in my south bridge?
Regards.
