Any idea what's going on? Things work fine under 2.2.14. Does it work in any other kernel, or is it new hardware? Can you mount any cd with: mount /dev/scd0 /mnt/<whatever ? cdrecord -scanbus might fail if you don't have scsi generic compiled (in-kernel or modules) or do not have /dev/sg[0-9]. 1. Check in your .config for CONFIG_CHR_DEV_SG=y in the "SCSI support" section. If it's not there, add it and rebuild the kernel. 2. A ls -l /dev/sg* should look like this: florin at bear:~$ ls -l /dev/sg* crw------- 1 root root 21, 0 Oct 15 01:01 /dev/sg0 crw------- 1 root root 21, 1 Oct 15 01:01 /dev/sg1 crw------- 1 root root 21, 2 Oct 15 01:01 /dev/sg2 crw------- 1 root root 21, 3 Oct 15 01:01 /dev/sg3 crw------- 1 root root 21, 4 Oct 15 01:01 /dev/sg4 crw------- 1 root root 21, 5 Oct 15 01:01 /dev/sg5 crw------- 1 root root 21, 6 Oct 15 01:01 /dev/sg6 crw------- 1 root root 21, 7 Oct 15 01:01 /dev/sg7 crw------- 1 root root 21, 8 Oct 15 01:01 /dev/sg8 crw------- 1 root root 21, 9 Oct 15 01:01 /dev/sg9 Cheers, florin -- "If it's not broken, let's fix it till it is." 41A9 2BDE 8E11 F1C5 87A6 03EE 34B3 E075 3B90 DFE4 -------------- next part -------------- A non-text attachment was scrubbed...
