plain 2.2.X: no ide CD-RW?

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

For a while now, I've been running a 2.4 kernel, but (for my research) I need to now run a 2.2 kernel. I was hoping to just run a stock 2.2.19, but I've found that I can't use my CD-RW drive, either as a plain IDE cdrom, or as a scsi-emulated one. (I have ide-scsi, ide-cd, and scsi all as modules.)

When I try things as scsi-emulated CD-ROM, I get the following:

  Jun 22 19:58:15 lydia kernel: ide-scsi: The scsi wants to send us
     more data than expected - discarding data
  Jun 22 19:58:16 lydia last message repeated 83 times

Instead, if I try ide-cd, I get these messages:

  Jun 22 20:11:38 lydia kernel: hdc: status error: status=0x58 {
     DriveReady SeekComplete DataRequest }
  Jun 22 20:11:38 lydia kernel: hdc: drive not ready for command
  Jun 22 20:11:38 lydia kernel: hdc: status timeout: status=0xd0 { Busy }
  Jun 22 20:11:38 lydia kernel: hdc: DMA disabled
  Jun 22 20:11:38 lydia kernel: hdc: drive not ready for command
  Jun 22 20:11:38 lydia kernel: hdc: ATAPI reset complete
  Jun 22 20:11:48 lydia kernel: hdc: irq timeout: status=0x80 { Busy }
  Jun 22 20:11:48 lydia kernel: hdc: ATAPI reset complete
  Jun 22 20:11:59 lydia kernel: hdc: irq timeout: status=0x80 { Busy }
  Jun 22 20:11:59 lydia kernel: end_request: I/O error, dev 16:00
     (hdc), sector 64
  Jun 22 20:11:59 lydia kernel: hdc: status timeout: status=0x80 { Busy }
  Jun 22 20:11:59 lydia kernel: hdc: drive not ready for command

I have these problems with 2.2.1[7-9] & 2.2.20pre5. However, if I add one of the IDE patches, all is well. 2.4 kernels have never given me these sorts of problems.

I have a 440LX motherboard (HP Pavilion 8260), hooked up to a Plextor PX-W8432T 4/8/32 CD-RW, attached as /dev/hdc. I also have an OnStream DI-30 as /dev/hdd, and a Maxtor 91020D6 10G drive as /dev/hda.

I can live with just running an ide-patched kernel, but it seems very odd that I can't even use the drive as an IDE CD-ROM drive with a stock 2.2 kernel. Is this a bug, or a limitation? I'd be happy to perform any tests to try and track this problem down.

Thanks!

Sorry, I was referring to the backport of the 2.4 IDE code to 2.2. I'm currently using ide.2.2.19.05042001 successfully, which I got from:

ftp://ftp.us.kernel.org:/pub/linux/kernel/people/hedrick/ide-2.2.19

I've used several similar patches, though. Stock 2.4 kernels work fine with my CD-RW as well; however, I've now discovered that plain 2.2 kernels do not. This could easily be a long-standing problem, probably at least a year old - I've only recently stumbled across it, though.

Since I have a solution (use the 2.4 IDE backport), this isn't critical; however, since many people still rely on 2.2, and I'd like to use a stock 2.2 kernel if possible, I'm willing to spend some time debugging this.

Thanks!

(A bit of background: Before I got my CD-RW drive last summer, I bought an OnStream DI-30 drive. This drive was then only supported on 2.2 with the 2.4 IDE backport, and so I've used this drive successfully with 2.2.16 + 2.4 IDE patch, and a similar combination since. Since stock 2.2.19+ now support this drive through the osst patch, I thought I'd try it out. It does work, but at the cost of losing my CD-RW.)
