cdrecord burn looks fine, but upon mounting, i get nothing.

[Jeffrey Forman]

i am having some issues burning cd's using cdrecord in 2.6.0-test5-mm4,
and possibly could get someone to lend a hand, since i'm not sure if
its a kernel issue or a cdrecord issue.

i am running 2.6.0-test5-mm4, on a p4-2.8/512MB machine. i have an atapi
plextor 48/24/48A ide cd burner.i am trying to burn various data, iso's
etc. cdrecord seems to burn correctly (paste of output below), but upon
trying to mount the burned cd, it shows up as 0 files on the cd. i am
using atapi burning with the command line: cdrecord dev=/dev/hdc -v
driveropts=burnfree speed=30 pentium4-1.4-20030911-cd1.iso. this
pentium4.iso is a gentoo release of its install. it is a 501MB file, but
when mounted, i see

Filesystem            Size  Used Avail Use% Mounted on
/dev/cdroms/cdrom0    246M  246M     0 100% /mnt/cdrom

Attached is a pertinent kernel bug report. Hopefully you can alert me as
to what i might be doing wrong, or if this is a kernel issue and totally
out of my hands. As expected, I can burn perfectly fine on my system
when running the 2.4.20 kernel released with gentoo systems now.

Any help you can give me is greatly appreciated. Please feel free to
pass this email on to other parties if they are more knowledgeable on
this issue. all help i have searched for so far has come down to "it works for me, not sure what your issue is."

please CC me personally as i do do not subscribe to the linux-kernel ML. 

Cheers and thanks in advance,
Jeffrey Forman
