The driver should be totally machine independent. I suspect that your problem might be a hardware problem -- the alpha might be a bit noisier in terms of EMI than a PC. Have you verified that it it works with another OS? (no, I don't know what other OSes are kind enough to tell you about CRC errors..)

I get this error when using an 80 wire udma66/100/133 cable to connect a maxtor harddrive. I verified this config as working in a normal pc, in the promise controller screen ( udma6 ). It looks like the driver doesnt do the correct udma133 initialization on alpha.
