I tried what you suggested, but it still does not work. I generated the symbols in the same directory as the kext while loading kext (did not need to use -n). I get the same error. -s.

This is preventing me from making any progress on debugging the kernel panic further.  I am trying to provide more information that seems relevant to me.

What if you try "add-kext" instead of "add-symbol-file"? Specify the path to the kext, i.e.

(gdb) add-kext ~/fsd/omfs.kext

...

sudo kextutil -arch x86_64 -s ~/fsd/symdir ~/fsd/omfs.kext

...but before you do that, build the symbols into the same directory as your kext, e.g.

sudo kextutil -n -arch x86_64 -s ~/fsd/ ~/fsd/omfs.kext

-n don't load the kext, just generate symbols

There were changes in both SnowLeopard and Lion to help search for kexts and their symbols (see a previous post by Jason Molenda in this mailing list) which perhaps means that putting your symbols in a different directory than the kext itself is confusing someone.

Good luck.
