Hi Barry,
When I upgraded to 2.6.19 (i think) all my PATA devices changed from being hd(abcd) to sd devices.. which sounds very much like what you're experiencing. I ended up booting a boot cd and changing my fstab and grub files and then it all worked again.

I have recently changed my mainboard to an Asus P5W DH Deluxe which includes both SATA and IDE interfaces. There are 2 IDE connectors of which one is controlled by an Intel chip and the other by a JMicron chip.
I have two IDE hard drives (hda and hdb) both on the same cable and connected to the Intel interface. I also have an IDE DVD Writer connected to the JMicron interface.
When Linux (kernel 2.6.20) boots it does not recognise the DVD Writer although I can get Knoppix 5.1 to boot from the DVD drive if I append irqpoll at the boot prompt after which everything seems to work. If I append irqpoll at the normal Linux boot prompt I get 'lost interrupt' messages when the system is starting and it seems to hang.
It also lists, in the logs, a device sda which does not exist. There is a SCSI card installed which drives a DAT tape drive but nothing else.
There are no SATA devices connected.
Is there a way around this JMicron problem (DVD not recognised) or do I have to wait for the JMicron drivers in the kernel to be improved?
What is this spurious sda device?

After reading a lot on the Internet and seeing other people with similar problems with JMicron and no solutions I'm not expecting much but there's no harm in asking.
Suggestions will be very much appreciated.
