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

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) ?
It doesn't look that serious 'I think', hit bugzilla and look at these for
more info #243238 #245426 add to or open at your leisure.
...dex
looking at those bugzilla entries the issue seems to be still unfixed; it is a serious
problem: every kind of cd/dvd access from that point onward requires a reboot.
Apparently libata is to blame; I'll recompile the kernel without libata
(hoping that both SATA and PATA are still accessible) until that bug is fixed
I had another thought. Unless this is a very old DVD it should be
running at more than UDMA/33, if it's reasonably new did you check that
it is on an 80 pin cable instead of a 40? There is a problem identifying
the cable in some hardware, and a trick to forcing the cable to be
treated as 80 pin. I probably have that put away somewhere, but I didn't
find it quickly.
You might have to search LKML for "80 pin cable" or similar. If it's an
old drive forget I said this. ;-)
