I have a problem with pata_via and a HL-DT-ST GCE-8525B cdrom, with kernels
2.6.22 and 2.6.23-rc3. When burning cds, the burning speed drop down to ~ 1.
Also I have problems readind cds.
With kernel 2.6.21, the cdrom work well.
There are not error messages in dmesg and /var/log/messages, only some error
when shutdown de pc(reseting port, ...).
I have also a HL-DT-ST DVDRAM GSA-4167B DVD that work well.
DVD(work well):
[root@jar ~]# hdparm -i /dev/scd0
/dev/scd0:
