| |
I've been having some problems with my SCSI CD-ROM writer. The drive is a Plextor (one of the FAQs or man pages I read before buying the drive said that it works - but I can't find that man page or FAQ now - but that's another story). When I try to write a CD in dummy mode the process stops at the stage where it's about to start writing the data (the CD-R has all lights off and doesn't seem to be doing anything). I tried removing the sg and sr_mod modules and then did a modprobe of sr_mod. The modprobe process got stuck in "R" state (according to ps), but I can't kill it. The load average is 1.00. Here's the lsmod output:
Module Size Used by sr_mod 18188 1 (uninitialized) cdrom 9916 0 [sr_mod] aha152x 25896 0 scsi_mod 47436 1 [sr_mod aha152x] af_packet 6572 0 (unused) sb 23820 0 (unused) uart401 5804 0 [sb] sound 66056 0 [sb uart401] softdog 1064 1 misc 720 1 [softdog] tulip 19668 1 isofs 17812 0 (unused)
Here's the tail of the dmesg output:
aha152x: BIOS test: passed, detected 1 controller(s) aha152x0: vital data: PORTBASE=0x340, IRQ=11, SCSI ID=7, reconnect=enabled, pari ty=enabled, synchronous=disabled, delay=100, extended translation=disabled aha152x: trying software interrupt, ok. scsi0 : Adaptec 152x SCSI driver; $Revision: 1.7 $ scsi : 1 host. Vendor: PLEXTOR Model: CD-R PX-R412C Rev: 1.02 Type: CD-ROM ANSI SCSI revision: 02 Uniform CD-ROM driver Revision: 2.12 Detected scsi CD-ROM sr0 at scsi0, channel 0, id 4, lun 0 sr0: scsi3-mmc drive: 12x/12x writer cd/rw xa/form2 cdda caddy eth0: No 21041 10baseT link beat, Media switched to 10base2. registered device ppp0 Detected scsi CD-ROM sr0 at scsi0, channel 0, id 4, lun 0
Any suggestions for how to track this problem down? Sure the CD-R doesn't seem to be operating the way I'd like, but the kernel should be able to handle this better than just getting a stuck modprobe process...
