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.
