>Environment:
	-current of today (2003-12-21) Running on a:
	Abit IC7-Max3
	Hyper threading is enabled, and a SMP kernel is being used.



>Description:
	When booting using the 3114 driver for the SATAlink, the kernel fails to recognise
	WD Raptor disks (disks work fine with the ICH5R interface):

wd1: dos partition I/O error

>How-To-Repeat:
	Install WD Raptor disks on a SATAlink 3114 chip.
>Fix:
	I think the disks work when wdc debugging/tracing is enabled, however that kind of tracing is rather verbose, and painful, and hard to see if it gives an indication of what's going wrong.
