Well, BIOS believes it's PATA . Anyway, that didn't change.

[gentoo-user] /dev/sr0 has disappeared: big mystery
For the 1st time in 2 months, I went to write a CD & discovered that /dev/sr0 is not being created nor symlink /dev/cdrom ; I looked at 'dmesg': no mention of 'sr' or 'cd' being found. I've searched the Forum (more noise than signal as usual) & Bugs: nothing. I tested the drive: SystemRescue 1.1.0 (kernel 2.6.25.16) starts correctly & mounts /dev/sr0 on /mnt/cdrom ; its 'dmesg' says : sr0: scsi3-mmc drive: 16x/16x writer dvd-ram cd/rw xa/form2 cdda tray \ Uniform CD-ROM driver Revision: 3.20 BIOS reports "Auto-detecting PATA primary master: ATAPI CD-ROM". I updated to Hal-0.5.11-r8 on 090221 & Udev-124-r2 on 090418 ; I recompiled Udev, but that made no difference. I've checked the files which mention 'cd' in /etc/udev/rules.d & there is no difference today from those at 090315 , when I did my last system back-up & last used the CD drive. I've checked my kernel configs for 2.6.25 & 2.6.29 using 'gvimdiff' & there is no difference between the relevant sections in Devices. I updated to 2.6.29 on 090404 . I tried my other kernels with the following unnerving findings : 2.6.25 creates /dev/sr0 , but after X starts the mouse/keyboard fail; 2.6.23 & 2.6.22 create /dev/sr0 , but X won't start at all. I notice that under 'Device Drivers -> ATA/ATAPI/MFM/RLL Support' there are the lines : generic ATA/ATAPI disk support (NEW) [*] ATA disk support (NEW) [ ] ATAPI floppy support (NEW) < > Include IDE/ATAPI CDROM support (NEW) I didn't say 'y' to 'ATA ... Support', so both config files (25 & 29) say # CONFIG_IDE is not set This is because I understood that if you have 'SCSI device support -> SCSI CDROM support' enabled, then you shouldn't have 'ATA...RLL' enabled as well. Is this a vital change in 2.6.29 ? Has anyone else encountered this ? Does anyone have suggestions ? -- ,, SUPPORT ___//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT`-O--O---' purslowatchassdotutorontodotca
