2.4.19: deleting files on hfs causes oops

Subject sez it all. Want more? you got it.

disk is a LS-120 superdisk, USB, Mac format, mounted under hfs. tried
to delete a file that wasn't being used. from syslog, looks like it was rm that did the damage. lsmod follows:

Thanks,

did you previously create the directory you deleted in? I am currently trying to pinpoint this bug, time permitting.

Regards
Oliver

Directory was already created prior to mounting the fs in the ls-120
drive. It was mounted rw, so removing a simple file shouldn't have been a problem. both directory and file pre-existed before the rm.
