error with hfs disk

[Bill Roberts]

Hello
I'm having a problem with an hfs (not hfs+) partition that I use to share=

between my mac and linux.
when I try to delete (rm) a file it returns "Illegal instruction"
then when I try to umount it (or restart the machine) it returns "device
busy"
my fstab line for that partion is:
/dev/hda13  /share	hfs  defaults  0  2

when I checked my messages log I found information about an error:

I'm not quite sure what most of this means...
I'm using yellowdog's 2.4.18 kernel, and the most recent hfsutils package=
.
(although I don't think I've ever used any the hfsutils progams...)
Does anyone know how I might try to fix this?
thanks in advance for any advice
