The document I found seems to be referencing PowerPC, I have an iMac 2011 (Darwin Kernel Version 13.0.0: Thu Sep 19 22:22:27 PDT 2013; root:xnu-2422.1.72~6/RELEASE_X86_64 x86_64) I am thinking about using subversion to store my source and work with adding I/O modules and Kernel Extentions for practice. If there is a simple explanation ( steps ) on accomplishing this it would be nice.

The steps for debugging a kernel panic are pretty much the same as before. You’d need the kernel debug kit. If you intend to use 2 machine debugging over the thunderbolt firewire adapter, you’ll need to set the nvram on the test machine to nvram boot-args=“debug=XXXX kdp_match_name=firewire fwkdp=0x8000 fwkpfv=0x8000" Hope that helps, David On Jan 5, 2014, at 12:00 PM, darwin-kernel-request(a)lists.apple.com wrote: > Send Darwin-kernel mailing list submissions to > darwin-kernel(a)lists.apple.com > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.apple.com/mailman/listinfo/darwin-kernel > or, via email, send a message with subject or body 'help' to > darwin-kernel-request(a)lists.apple.com > > You can reach the person managing the list at > darwin-kernel-owner(a)lists.apple.com > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Darwin-kernel digest..." > > > Today's Topics: > > 1.

I've done this before on Snow Leopard via gdb, but am having problems figuring out how to do so with lldb. Can anyone give me a set of steps for debugging using lldb assuming I have the kernel panic log, similar to what's defined here (https://developer.apple.com/library/mac/technotes/tn2063/_index.html#//appl… Thanks for any help. > > Jeff >
