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! --Anil (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.) - -- Anil Somayaji (somayaji@sprintmail.com) http://www.cs.unm.edu/~soma +1 505 872 3150 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) iEYEARECAAYFAjs2h2AACgkQXOpXEmNZ3SfOlwCfb+it3YQrmO2e9q14AZMhcdZo M+0An3Mi8aoEkvjD5vhC3Hc6yaICrMDE =cV6C -----END PGP SIGNATURE-----
