Hello,
I have an Asus Commando Mobo with one of those dreadful JMicron
controllers (JMicron 20360/20363 AHCI Controller (rev 02). I have a
PATA ATAPI CD-RW attached to the JMicron. I'm running 2.6.21 vanilla
with no modules, everything built-in
I can't get my CD-RW to work. have tried the pata_jmicron driver and
the JMicron ide driver, no success.
With the pata_jmicron, there are timeouts and resets in the dmesg, as
can be seen below:

Excerpts from lspci:

Some relevant .config options:
CONFIG_ATA=y
CONFIG_SATA_AHCI=y
CONFIG_PATA_JMICRON=y
Other relevant info: I use the libata ahci driver to run my sata ports
and that works great.

This is almost certainly a problem outside of the IDE handling in that
case. The jmicron controllers are smart, there is basically no code to
the IDE driver to go wrong (especially in the case of using the old IDE
for the PATA port where you basically use zero code that hasn't been
tested for years).
Do you get the odd timeout or continuous timeouts ?

Could this be a hardware problem then? The CD-ROM is recognized by
BIOS and I'm able to boot bootable CDs fine.
Could it be a setting in BIOS? I did try to switch from Enhanced to
Compatible mode, but problem persists.
With the ide driver, the device is recognized, but when I attempt to
mount it, il times out, gets reset and my machine locks up at times.

With the pata_jmicron, the device is not recognized. I get the
timeouts only during the probing during the boot phase.

The old IDE driver for JMicron didn't work well for me either,
running on Kubuntu Edgy 2.6.17. It would find the PATA DVD drive,
and work okay for the first half of a DVD movie playback, and then go bonkers.
I eventually gave up on it and installed a pure SATA DVD drive on ICH7(8?)
and just disabled the JMicron completely.
Kernel upgrades are not currenly a viable option for this box
(too many other things would need to be fiddled with).
Cheers

"go bonkers" being ? (and did you keep any dumps of it ?)
