Hi,
The pata_pcmcia problem is fixed. Thanks!
(I tested it on kernel 2.6.20-git14)
But kernel 2.6.20-mm2 introduced new oops
when I insert the pata_pcmcia device.

Any chance you could insert some printk() calls into ata_apci_exec_tfs?
ata_exec_internal_sg() never calls that function, so I'm curious if
something corrupted memory a bit, or what happened.
In any case, I'm surprised that ACPI would be executing taskfiles on
PCMCIA anyway.
