SubjectRe: IDE-UDMA error
Date

According to the Linux Multi-Disk HOWTO many motherboards
connect the data lines of both channels together.
You are using both channels, so the 45cm limit could be
total for both channels. There are other tips there,
it's worth reading.

This was the culprit: with only one cable it worked fine (and UDMA
gave 20 % more throughput with hdparm -t). Maybe this can be
documented somewhere more prominently, eg, in Configure.help?

Should I submit a patch? (to whom?)
