kernel BUG at buffer.c:2497! - mounting hfs formatted CD

Hi,

I'm getting the following oops while trying to mount a hfs formatted CD 
(produced on Mac OS X). mount segfaults and I have to reboot to get my CD 
back.

I've found postings about this exact problem in the archives happening with 
2.4.17 and .18, but I didn't find a fix or patch for this. Does any patch 
exists to fix this problem?

Here's the output of ksymoops:

ksymoops 2.4.5 on i686 2.4.19.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.19/ (default)
     -m /usr/src/linux/System.map (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.
