I tried this, and couldn't reproduce the problem since. Fine! But,
what I don't understand: connecting both disks to the same channel
(as master & slave) on the mainboard seems to work fine; if they are
connected to separate channels (both as master) on the mb I get

viaide0:0: lost interrupt
        type: ata tc_bcount: 8192 tc_skip: 0
viaide0:0:0: bus-master DMA error: missing interrupt, status=3D0x20
viaide0:0:0: device timeout, c_bcount=3D8192, c_skip0
wd0a: device timeout writing fsbn 64852684 of 64852684-64852699 (wd0 bn 648=
52747; cn 64338 tn 0 sn 43), retrying
wd0: soft error (corrected)

Is this more likely a problem with the chipset or with the disk?

However, using the Promise seems to work (around the problem...).
Thanks!
