Mounting hfs cdrom

[Mourn]

Hello,

As I received the same error with different kernel version and
compilation, I thought I had to send you this report.

For information, my kernel is a 2.4.22-grsec with pax enabled.
When I try to mount in loopback mode an iso of an hfs cdrom, it works
well, but when I try to mount directly the cdrom, I obtain a kernel BUG
message. If I re-use mount after that, my kernel finally panics.

Here is the message I obtain when I try to mount an HFS cdrom :
