IDE CD-ROM/CD-RW troubles - lost interrupts, looong waits


Lately, I've been trying to get k3b working, so I can burn CDs conveniently. The CD drives in question are a Kenwood True-X "72x" CD-ROM (Second IDE master) and an HP 9100 CD writer (Second IDE slave).

The problem is that k3b takes fooooooorever to start up, because it checks the CD devices using cdrecord, and that causes hdc (the Kenwood CD-ROM) to wig out. The drives otherwise work fine. I can mount CDs on both drives, read & copy files, and I can burn CDs with the CD-RW drive. But when k3b starts up, it sits for a long time, as if it hung, though eventually starts in 2 or 3 minutes. In the meantime, I get lots of errors on the console and in the logs:

Oct 10 16:35:30 localhost kernel: ]
Oct 10 16:35:30 localhost kernel: ide-scsi: expected 2 got 4 limit 2
This is highly annoying. Any suggestions on how to make my CD drives play well with others?

Its more like getting k3b to play nice, I have the same problem with a 52x24x52 Plextor drive, all of the other GUI burner programs work fine, but k3b either times it out or more fun... coasters unless I set the speed for 6x. As far as I can tell its not a hardware problem, and since k3b is just a gui wrapper for cdrecord, its all in the cdrecord queue commands that k3b is sending to cdrecord. I never bothered to debug it, I just switched to xcdroast or gcombust, although a tool around the k3b page and a newer version may help out.

Cheers,
