About a week ago I posted to the redhat-list about problems I was having
shutting down my machine. At the time, I hadn't a clue what was causing
my machine to not respond to a shutdown command and my load average had
jumped to 11.00. The machine was still quite useable.
However, since then, a kind reader enlightened me that something was
probably sitting in a disk wait mode. Well, I've been able to figure out
that my CD-RW isn't behaving properly at all. I have been able to burn
one good CD off it ever (out of about 20 tries) and I thought I was doing
somethign wrong but perhaps not.
However, since I am using what is probably considered an unsupported OS
with the CD-writer, I want to verify that it is indeed a CD-RW hardware
failure and not my card, a buggy driver, or a buggy cdburning program.
Relevant info:
Kernel 2.1.131
Adaptec 2940UW SCSI card
Ricoh 6201S CD-RW
using Xcdroast-0.96e (also tried using mkisofs and cdrecord-1.6.1 manually
- same problems)
Original problems I was having was the disc I burned never matched the
image I used when I compared them. Now, I am getting kernel error
messages in /var/log/messages. I do not know how to interpret SCSI error
messages, although I would be delighted if someone could point me to a
good reference that I could read and figure out the messages.
Here is the typical message:
Dec 14 10:01:05 marble kernel: sr0: disc change detected.
Dec 14 10:01:25 marble kernel: SCSI CD error : host 0 id 1 lun 0 return

The following also periodically pops up in the logs:
Dec 11 09:52:49 marble kernel: (scsi0:0:0:0) Data overrun detected in

As well as the following (hda is my CD-ROM):
Dec 9 10:43:56 marble kernel: hda: command error: status=0x51 {
DriveReady SeekComplete Error }
Dec 9 10:43:56 marble kernel: hda: command error: error=0x54

key=0x05)
Dec 9 10:43:56 marble kernel: Illegal mode for this track -- (asc=0x64,
ascq=0x00)
Have there been a rash of reports related to CD hardware problems with
kernel 2.1.131 or is it isolated to a CD burner that is failing in my
setup?
I apologize if this is a FAQ but I want to rule out a software bug before
I try to get the CD-burner replaced, especially if it is a bug in the
development kernel and 2.2 release is just around the corner.
If you are replying to me from the linux-kernel, please do so by email, as
the volume of the list was too much to keep up with and I'm not subscribed
to it anymore.
I can provide more relevant information if necessary.
Thanks for any help.
