Hm, do you think you could upload (or attach) your /usr/lib/debug/boot/kernel/kernel.debug and provide an updated panic trace using that same exact kernel? I would also need to know the exact revision of your code base and what patches you have applied. Might be easier to use a plain build of FreeBSD without any patches. > > > After attempting to resolve the address, can you give the attached > > patch a try?

So you still got the same panic trace with the patch applied? Trying to figure out whether there could be multiple issues. Thanks, Roger.
