Hi,
The ata driver tries to enable UDMA for my controller, but fails
(this is no disk problem. The disks can do UDMA, as tested in
another machine). Perhaps UDMA should be disabled for all
VIA 82C586 chips:
dmesg output:

This already with a small patch with only uses WDMA modes, otherwise I
will
get "lost disk contact" messages.
