non functional pata dvd drive under 2.6.25.6

non functional pata dvd drive under 2.6.25.6

[Jeroen Beerstra]

hi there,

I've filed this as a bug with redhat bugzilla (12-6), https://
bugzilla.redhat.com/show_bug.cgi?id=451081, but so far I've had no 
response at all ... so here we go ;)

Basicly my ide dvd writer is non functional with Fedora 9 (kernel 
2.6.25.6). So far I've seen it functional only once when I booted with 
media already inserted, but for the rest it's pretty much like this:

cat /sys/bus/scsi/devices/10:0:0:0/model 
PATA 20X20X12X 

The drive is completely non functional.

System is a Nforce 780i SLI MB (Asus P5N-T Deluxe) with an Q9450 INtel 
Core2 Quad CPU and 4 GB of ram.

With Windows XP/Vista there are no problems with this drive and also I 
had no problems installing Fedora from this drive in the first place, so 
I doubt if it is a hardware problem. 

I can live with the fact that I only have one writer available but not 
with the fact that everything that tries to access the drive hangs with 
status D for a very long time, hald-addon-storage for one....

Hmmm... the problem could be caused by hald polling for media presence.
 Does "hal-disable-polling /dev/srX" make any difference?
hal-disable-polling setting is persistent so if your drive goes bonkers
quickly after boot, you can disable polling, reboot and see whether
anything is different.  Also, please post the result of "lspci -nn" and
"hdparm -I /dev/srX" && please try 2.6.26.

Thanks.

I'm pretty sure about that since the hald process I'm refering to points to 
the 'faulty' drive. However simply booting with noapic seems to fix all of my 
problems.

See:

Bug 451081 @ bugzilla.redhat.com
Bug 11044 @ bugzilla.kernel.org

There are lots of similar reports. I don't know what broke the APIC code
but it doesn't appear any of these are libata bugs.

As soon as I have my system back and running again I will test the patch
that was attached to the rh bugzilla report, perhaps that will make things
a bit clearer.
