I've been having a heck of a time trying to burn CDs under Fedora Core 3. I'm using a Thinkpad X22 laptop and an Iomega ZipCD 650 USB CDRW drive. When trying to burn a CD with FC3, I notice a few problems: First, the fstab entry and moutpoint that gets automatically generated: /dev/scd0 /media/zip auto pamconsole,exec,noauto,managed 0 0 Apparently, FC3 thinks the CD burner is an actual zip drive. (Some brain damage in the scripts that create these device entries?) That, however, is a minor annoyance. The major annoyance comes in the form of lockups, kernel panics, and/or bizarre behavior. Here's dmesg output from pluggin the drive in: scsi0 : SCSI emulation for USB Mass Storage devices Vendor: IOMEGA Model: ZIPCD 650 USB Rev: I2,2 Type: CD-ROM ANSI SCSI revision: 02 USB Mass Storage device found at 4 usbcore: registered new driver usb-storage USB Mass Storage support registered. sr0: scsi3-mmc drive: 8x/8x writer cd/rw xa/form2 cdda pop-up Uniform CD-ROM driver Revision: 3.20 Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0 sr0: CDROM not ready. Make sure there is a disc in the drive. cdrom: open failed. sr0: CDROM not ready. Make sure there is a disc in the drive. cdrom: open failed. ... Apparently, something keeps trying to mount the (nonexistant) CD in the drive and keeps failing, as this just repeats. If you try to put a CD in, well, good luck - the door recloses as soon as it opens - making it next to impossible to feed it a CD. If you DO manage to get a blank CDR in there, dmesg output switches to this: end_request: I/O error, dev sr0, sector 0 Buffer I/O error on device sr0, logical block 0 end_request: I/O error, dev sr0, sector 0 Buffer I/O error on device sr0, logical block 0 SCSI error : <0 0 0 0> return code = 0x70000 SCSI error : <0 0 0 0> return code = 0x70000 end_request: I/O error, dev sr0, sector 0 Buffer I/O error on device sr0, logical block 0 Buffer I/O error on device sr0, logical block 1 Buffer I/O error on device sr0, logical block 2 ... If, heaven forbid, you try to burn anything to that CD, you get either a kernel panic or sometimes a system hang. I haven't captured that one. WORKAROUND, in case anyone else has been bitten by this: service haldaemon stop After stopping the haldaemon service, the CDRW works as expected. No weird behavior, no system hangs, and no weird error messages. Anyone else experienced this sort of thing with Fedora Core 3? Possibly relevant packages: hal-0.4.2-1.FC3 kernel-2.6.9-1.698_FC3 (from testing - was hoping that would fix my USB woes) -- -------------------------------------------------------------------- * Charles Taylor <tomalek@xxxxxxxxxxxxxx> * Chemistry teacher, Linux enthusiast! -------------------------------------------------------------------- * Web: http://home.mindspring.com/~charletiv/ --------------------------------------------------------------------
