Problems with JMicron-PATA-controller

Question

Hi..
Two weeks ago I purchased new PC-components.
My new mainboard is an ASUS P5K Deluxe
It has a JMicron PATA-Controller onbaoard..
My two IDE-drives (DVD-rom and DVD-writer) are connected to this controller
[XazZ@darklight ~]$ lspci | grep IDE
03:00.1 IDE interface: JMicron Technologies, Inc. JMicron 20360/20363 AHCI Controller (rev 03)
Now this message spams my dmesg:
hda: cdrom_pc_intr: The drive appears confused (ireason = 0xd0). Trying to recover by ending request.
hda: cdrom_pc_intr: The drive appears confused (ireason = 0x01). Trying to recover by ending request.
hdb: cdrom_pc_intr: The drive appears confused (ireason = 0x01). Trying to recover by ending request.
hdb: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hdb: drive not ready for command
hdb: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hdb: drive not ready for command
hdb: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hdb: drive not ready for command
hdb: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hdb: drive not ready for command
I already searched for a solution - and someone suggested to add pci=routeirq to the kernel command-line (in my menu.lst)
I did that but it had no effect
In my kernel-config I activated the following options:
Device Drivers  ---> <M> Serial ATA (prod) and Parallel ATA (experimental) drivers  ---> <M>   AHCI SATA support
<M>   Intel ESB, ICH, PIIX3, PIIX4 PATA/SATA support
<M>   JMicron PATA support
If you need more information - just tell me
Thanks in advance

Thanks for the reply
I think you are right
But I solved my problem a bit different:
After I've read your post I wanted to disable the old jmicron module in my kernel-config but I couldn't find it...
Then I opened
linux-2.6.22/drivers/ide/pci/Makefile
with an editor
There I've removed the following line:
obj-$(CONFIG_BLK_DEV_JMICRON) += jmicron.o
After that I've saved the Makefile and build my kernel
-> Works nice until now (tested it for ~30 - 45 minutes) - no dmesg spam anymore
After patching the Makefile:
[XazZ@darklight pci]$ lsmod | grep jmicron
pata_jmicron 4608 0
libata 108084 3 ata_generic,pata_jmicron,ahci
Before I patched it, only the module jmicron was loaded (pata_jmicron *wasn't* loaded)
Thanks for your hint/solution
