Alpha should not be operationally much different from other little

The PCI swizzle might be weird (what is your Alpha platform?), is the
only Alpha-specific thing that comes to mind.
I am using a DS20 (Tsunami / Goldrush).
I have similar such behavior before when using drivers that generate
many unaligned accesses - I only have seen 2 places they occur in
sata_sil24 and have fixed them myself, but that made no difference.
We definitely want to fix all these you find. Please post more info...
In sil24_config_port, the writel's for /* zero error counters */ should
be writew's - they are 16bit control registers.
Only PORT_DECODE_ERR_THRESH and PORT_CRC_ERR_THRESH appear to be
unaligned, but why risk a stl when a stw (on platforms that support it)
can be used.
Also, if you are highly motivated, I would love to see if other SATA
cards have similar problems on Alpha...
I'll need to find a computer store with a decent return policy, but I
would consider doing it ....
