kern/177876: [mips] kernel stack overflow panic on mips64, EdgeRouter Lite

[Adrian Chadd]

Do an svn log in sys/mips/ or sys/vm/ and look at the changes.

I don't know how far you can go back before you don't have the
edgerouter lite support, but maybe you can try going back to when Juli
initially committed it, and then just work your way forward.

I think Juli did the initial work, so she knows when it came in.

juli - I don't suppose you could spin up FreeBSD-HEAD on the
edgerouter lite and take a look? It's highly likely someone messed up
since you did your port. :(

Thanks,



adrian
