I've discovered this comment by Andre Hedrick and another by Alan Cox:

"This is what it tells you directly. You have dirty crosstalk on your ribbon. Basically nothing is wrong, except you can not safely support that transfer rate."

"BadCRC is normally a cable error, but I'm suspicious that its also one of the things caused by PCI bus problems on the VIA stuff"
The thing is though how can it be such a short step between a few CRC errors and the IDE bus going into Autistic mode.
