big problems with Via-ide and dvd

[Nico Sabbi]

Hi,
the driver for my Via 8237a sata/ide controller seems to have huge
problems with my ide dvd drive: often during reading
-but also just after the plain insertion od a dvd- I see messages like
the following in the log:

Dec 30 13:12:05 xp kernel: ata4.00: exception Emask 0x0 SAct 0x0 SErr 
0x0 action 0x2 frozen
Dec 30 13:12:05 xp kernel: ata4.00: cmd 
a0/00:00:00:00:20/00:00:00:00:00/a0 tag 0 cdb 0x0 data 0

Dec 30 13:12:05 xp kernel: ata4: soft resetting port

Dec 30 13:12:06 xp kernel: ata4.01: configured for UDMA/25
Dec 30 13:12:06 xp kernel: ata4: EH complete

and obviously the dvd drive becomes unaccessible.
The 2 Sata disks work perfectly (so far).
The drive is not broken, as Solaris on the same pc has been working
perfectly for a long time.

Does anyone know how I can solve my problems?

Thanks,
	Nico
