Hmmm... Once properly initialized, ahci is highly unlikely to cause

libata enables SCSI host during ATA host activation which happens
after IRQ handler is registered and IRQ is enabled. All ATA ports are
in frozen state when IRQ is enabled but frozen ports may raise limited
number of IRQs after being frozen - IOW, -freeze() is not responsible

Jeff, Alan, Mark and Albert, do you have ideas how we should support

other rubbish.

The err_mask is AC_ERR_DEV indicating that the device raised aborted the

Can you change #undef ATA_DEBUG in include/linux/libata.h to #define

So, this is specific to SATA (the host side at least) piix PIO READ,

That's probably because it's a mdma2 device, and not many chipsets seem

My experience with PATA drives and CF cards, it that they
default to PIO4 (assuming they report supporting PIO4).
So we don't actually need to do a set xfer mode on them.
