Subjectcdrecord with LSI53C1010 and Yamaha CRW2100S
From
Date
I have been unsuccessful trying to burn a CD-R since upgrading my
computer and I'm not sure where to go with this. I decided to try here.
I suspect a problem with the SYM53C8xx driver, and I think there may
also be additional problems elsewhere. My old system worked. It was:

RedHat 7.0 with 2.2.19 kernel
ASUS P2B-DS (440BX chipset) with 2 600MHz Intel processors
On-board Adaptec AIC-7890 with the new aic7xxx driver
Add-on Adaptec 2940 PCI adapter (narrow devices attached here)
Yamaha CRW6416S CD writer

My new system:

RedHat 7.1 with 2.4.8-ac11 kernel
Tyan Thunder HEsl S2567 (ServerWorks chipset) with 2 1000MHz Intel
processors
On-board LSI 53C1010-66 (running at 33MHz) dual channel SCSI
Add-on LSI21003 with 53C1010-33 (narrow devices here)
SYM53C8xx driver
Yamaha CRW2100S CD writer

I looked for problem reports with the 2100S and didn't see any, rather
several reports that it worked okay. I updated the firmware to the
latest - 1.0N and it didn't help.

I have tried several versions of cdrecord including the latest 1.11a05
with associated tools to no avail.

When I try burning a CD, sometimes I get errors and sometimes it appears
to work. When I try to mount a CD-R that burned successfully in a
Toshiba DVD-ROM drive, I get errors like this:

[root@lh2 /root]# mount /mnt/cdrom
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
or too many mounted file systems
[root@lh2 /root]#

And in /var/log/messages:

I tried replacing the LSI21003 with a 2940 and burned a CD-R. The
process went smoothly with no errors reported. I mounted the burned CD
in the Toshiba successfully and listed the contents. I did not think to
verify the CD with the mastered file. I then switched back to the
LSI21003 and tried to mount the burned CD-R. I got:

[root@lh2 /root]# mount /mnt/cdrom
mount: Not a directory
[root@lh2 /root]#

And in /var/log/messages:

Any help would be appreciated, and if anyone needs additional
information I will be glad to do what I can.
