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:
PCI: Setting latency timer of device 0000:03:00.1 to 64

Excerpts from lspci:
03:00.0 SATA controller: JMicron Technologies, Inc. JMicron
20360/20363 AHCI Controller (rev 02) (prog-if 01 [AHCI 1.0])
Subsystem: ASUSTeK Computer Inc. Unknown device 81e4
03:00.1 IDE interface: JMicron Technologies, Inc. JMicron 20360/20363
AHCI Controller (rev 02) (prog-if 85 [Master SecO PriO])

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.
