Hello,
please CC me, I'm not subscribed.
If any kernel developer is interested in more specific information
please mail me, I can build kernels, I can apply patches, though
have not done it regularly.
I'd like to get the DVD drive working somehow. I have googled a lot
and did not find any more ideas what to do. Some good keywords to
find a solution would suffice at that end.
Rough problem description:
I have a Tyan mainboard with NVIDIA chipset CK804. The only
SATA/IDE device is a SATA DVD combo, the harddisks are on a RAID
controller from 3ware. The harddisks are fine.
The openSuSE 10.3 boot dvds fail after booting from the BIOS, the
installation kernel cannot use the DVD drive. That kernel uses
libata and sata_nv pata_amd as drivers. The drive is recognized
but it cannot be used. This is the situation probably during
install from DVD and now in the running system after a network
install it persists.
Reading from the dvd device /dev/sr0 with dd stops after at most
119kb of rubbish read. Mounting fails with superblock not found.
When trying to remove the pata_amd module I get an Oops. I tried to
remove the modules to have a chance to reload them with other
options (atapi_enable), but that did not help, even after
rebooting.
A vanilla 2.6.23.1 kernel behaves even less friendly, the dd
on /dev/sr0 causes a hard reset.
So there are clearly some problems with libata in this system.
I have failed switching away from libata getting the drive to be
recognized at all.
Thanks for any help,
Bernd Strieder
