The following reply was made to PR alpha/34948; it has been noted by GNATS. From: Andrew Gallatin <gallatin@cs.duke.edu> To: sten spans <sten@blinkenlights.nl> Cc: freebsd-gnats-submit@FreeBSD.ORG Subject: Re: alpha/34948: Promise TX2 ATA133 controller doesnt work with 80 wire cable on alpha Date: Thu, 14 Feb 2002 19:14:38 -0500 (EST) 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..)
