Description Steve Bangert 2002-12-15 01:24:49 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.79 [en] (X11; U; Linux 2.4.20-rmap15b i586)

Description of problem:
I've got a Sony Spressa cdrom burner model #CRX100E/X that worked fine under
RH-7.1 and RH-7.2 (except for a problem with the scsi-cdrom module failing to
load on boot about two thirds of the time, which required another reboot or two
until the module would finally load) on RH-7.3 and RH-8.0 I am unable to mount
the device and just get
an error " unable to mount device, bad super block, etc,etc" and when using
Xcdroast it fails to recognize any media. I have traced the problem to version
1.44 of transport.c that was first introduced in kernel 2.4.19-pre3 and then
backported to the RH-2.4.18.xxx kernels. All vanilla kernels 2.4.19-pre2 and
older work fine!

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

How reproducible:

Steps to Reproduce:
1.plug-in cdrom, turn it on
2.boot RH-7.3
3.try to mount USB CDROM

Actual Results:  unable to mount USB cdrom

Expected Results:  should be able to mount device, Xcdroast shpould be able to
recognize cdrom media

Additional info:

problem started with version 1.44 of transport.c or 1.17 of transport.h

Thanks to Alan Stern this matter is solved, see the latest attachment, is there
any chance that this patch could be applied to the latest beta (pheobe) kernel
before RH8.1 is released, this patch should help a lot of people.
