Have you tried running without "-R"? I found that trying to create a
CDROM Image with Rock Ridge extensions failed on my NetBS/mac68k system,
although without a Kernel panic. In my case the CD wasn't recognized by
NetBSD as having Rock Ridge extenions recorded on it. I verifed this with
both mkisofs version 1.05 and version 1.11. Version 1.05 running against
the same filesystem on a FreeBSD system created the CD image without
error which was recognized by NetBSD (both i386 and mac68k ports) has
having Rock Ridge extensions. My conclusion is that there is a byte
ordering problem in mkisofs. I've submitted a PR and sent a detailed
E-Mail to the author.
