If you try to load both the pata_atiixp and the ahci driver
(for the same ATI SB600 adapter), very strange things happen.
The AHCI driver churns for three minutes or so, spewing
messages like this, then nothing works:
<6>ata3: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
<4>ata3.00: qc timeout (cmd 0xec)
<4>ata3.00: failed to IDENTIFY (I/O error, err_mask=0x104)
Shouldn't it be able to tell the device has already been
claimed by some other driver?
One would assume it'd fail to grab the PCI IO ranges twice? I haven't
looked at the code but I have seen this bug mentioned elsewhere so I
might well end up having to do that yet :-)
