------- Comment #40 from [EMAIL PROTECTED]  2007-12-11 17:09 -------
Setting mode to PIO0 is done right after reset because we don't know the drive
state at that point.  This caused problem w/ cable detection using ACPI or BIOS
setting because programming PIO0 on pata_amd clobbers DMA mode setting too and
we lose BIOS/ACPI setting before looking at them, so the fix was to cache _GTM
value while initializing controller before initiating probing sequence
(init_gtm).

It seems that Torsten's problem will be fixed by init_gtm but unfortunately
that thing is queued for 2.6.25 merge as it involves a bunch of other changes. 
I guess we'll have to backport init_gtm part to fix this one.  I'll get to it.
