Description of problem:
Having built an iso fs with mkisofs to provide both rockridge, joliet and hfs
support, a loop back mount using hfs works fine.
However burning to cdrom and mounting -t hfs /dev/cdrom causes kernel BUG report.
CD works fine in iso9660 mode.
Version-Release number of selected component (if applicable):
Linux jenjen3.localdomain 2.4.20-20.9 #1 Mon Aug 18 11:27:43 EDT 2003 i686
athlon i386 GNU/Linux
Steps to Reproduce:
1. Build isofs with:
mkisofs -r -J -l -D -L -V volid -hfs --macbin -o /home/tmp/dual-hfs-01.img
2. Check with loop back
mount -t hfs /home/tmp/dual-hfs-01.img /mnt/wrk -o loop,ro
3. Burn CD-R using xcdroast

driveropts=burnfree -v -useinfo speed=40 -dao -eject -pad -data
4. Mount CD defaults to iso9660 - no problems
5. Mount CD as type hfs gives log entry:
Sep 24 15:47:04 jenjen3 kernel: kernel BUG at buffer.c:2618!
Sep 24 15:47:04 jenjen3 kernel: invalid operand: 0000
kernel bug causes all subsequent mounts to hang; shutdown also hangs on unmount;
manual restart has to recover disks.
Access to mounted files from the CD as were available from the image looped back.
The CD has a large number of files, quite a number with long file names.

system log for kernel BUG at buffer.c:2618!
I have rebuilt the iso image with '-part' but to the same effect.
However I have found (by mistake) that 'mount -t hfs /dev/cdrom /mnt/wrk -o
loop' works. Strange?
The CD reads fine in a Mac OS 9.1 machine (only the without -part was tested).
Repeatable without all the proprietory binary modules loaded ?

untainted dmesg output
My apologies for submitting a tainted report.
I have tested without the tainted modules and the kernel BUG still occurs.
I find that the fault still occurs in single user mode. The dmesg output is
The fault does not occur when the kernel boot parameter 'hdc=ide-scsi' is
removed. Full X11 and running the application off the HFS mounted CD rom is
This is repeatable without all the proprietory binary modules loaded.
Please provide a copy of your /var/log/messages from a full boot, as well as
the full output from "lsmod > lsmod.txt". If you're using X on this machine,
I have an idea also, please attach your /var/log/XFree86.0.log as I'd like to
compare it with another bug report received.
