When I try to boot the Slackware 12.1 installation DVD, I get this error when it tries to set up my DVD burner (note the only drives I have are a hard drive as hda and the burner as hdc).

hdc: status timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hdc: ATAPI CD-ROM drive, 0kb cache
Uniform CD-ROM driver Revision: 3.20
hdc: status timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hdc: drive not ready for command
hdc: status timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hdc: drive not ready for command
hdc: status timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hdc: drive not ready for command

At the end of the boot, I can run setup and do everything up to the point where it tries to install the packages. Then it complains it can't find a drive with the Slackware CD/DVD in it. When I point it directly to /dev/hdc it can read the filename of the package but throws an error when it tries to install it. Imagine my joy after I had already dusted the root partition of a perfectly functional 12.0 install.

Thinking that it might be a problem with the DVD I burned, I reinstalled 12.0 and then followed the manual upgrade instructions. Upon rebooting the installed kernel threw the same error. I ended up nuking it all over and reinstalling 12.0.

When I boot with the 2.6.25.3 kernel I compiled myself, this is what I get instead:

hdc: ATAPI 40X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache
Uniform CD-ROM driver Revision: 3.20

I suppose I could have just compiled 2.6.25.3 all over again and not even used the stock kernel, but that was actually one reason for me to upgrade--so that I wouldn't have to do that.

Any thoughts on a workaround?

While this isn't Slackware-specific, it seems to be a bug with the 2.6.24 kernels and certain DVD drives (Benq ones seem to be mentioned most often. IIRC, my Sony DRU-810A is a rebranded Benq). Here's a couple of links. I'm going to try the suggested fixes.

I tried all of the suggestions in the links above but none of them works. It seems like my only option is to do a manual upgrade--something that I am somewhat loathe to do. If I would go that way, could I use the 2.6.25.3 kernel that I compiled under 12.0 or would I need to recompile it under 12.1 because of the change in kernel headers, glibc, or some such?

Well, I finally got 12.1 installed. I had to do it the hard way, by manually updating following the instructions in the UPGRADE.TXT file. I'm using a custom-compiled 2.6.25.3 kernel because none of the workarounds for the 2.6.24.5 kernel that comes with 12.1 will make my CD/DVD drive work with it. Was it worth all of the effort? Quite honestly, right now the jury is out. I probably should have just stuck with my perfectly functional 12.0 install. My main reason for wanting to upgrade is for the kernel upgrade, but that just plain didn't work.

Edit: I have found one nice benefit: Cedega works simply by installing the package now. I don't have to add any extra bits to Python to get it to work.
