Hi,
I have those very frequent resets when accessing my IDE dvd, especially
(but not only) after a cold boot.

UDF-fs INFO UDF 0.9.8.1 (2004/29/09) Mounting volume 'ATONEMENT', timestamp 2007/11/09 03:21 (103c)
ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen

         res 40/00:03:00:00:00/00:00:00:00:00/b0 Emask 0x4 (timeout)

ata3.01: configured for UDMA/33

Kernel is: Linux xp 2.6.23.9-85.fc8, but the same thing happened with
every kernel come out.
Chipset is:
00:0f.0 IDE interface: VIA Technologies, Inc. VT8237A SATA 2-Port Controller (rev 80)
00:0f.1 IDE interface: VIA Technologies, Inc. VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 07)

What can I do to remove the cause of this problem (except changing motherboard) ?

Thanks,
	Nico
