Description Rick 2002-11-17 08:09:43 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 Galeon/1.2.6 (X11; Linux i686; U;) Gecko/20020827

Description of problem:
  After updating the kernel to 2.4.18-17.8.0 and then to 2.4.18-18.8.0 using
errata, I received the following error when trying to burn a cd:

   cdrecord: No such device. Cannot open '/dev/pg0'.  Cannot open SCSI driver.

  If boot back into Redhat with the kernel that came with my redhat 8.0
installation CDs, which is 2.4.18-14, then I can record cd's all day long with
the same drive without any errors at all.  Both of the newer kernels, however,
report the above given problem.  The permissions on /dev/pg0 have not changed.
  I don't think you will be able to reproduce the problem without having my
setup, but hopefully you can make some sense out of the error message combined
with the fact that it only happens with two latest Redhat kernels, not the
original with 8.0.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.type cdrecord -scanbus

Actual Results:  cdrecord: No such device.  Cannot open 'dev/pg0'.  Cannot open
SCSI driver.

Expected Results:  No errors from scanbus, and I am able to record CDs.

  After booting back into 2.4.18-14 version of the kernel here is the actual
output of the cdrecord -scanbus entry that is not working in the two latest
kernel versions.  The below is the "good" expected results:

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
