I'm running NetBSD 2.0 on a dual 450MHz G4 (gigabit ethernet).  When executing 
ogg123 or firefox, I get a kernel panic:

panic:  lockmgr: locking against myself

Interestingly, this also happens during the "make install" step for the
firefox package.  This is reproducible every time.  The problem goes away if 
I boot into a single cpu kernel.

I wasn't able to find anything about this on the mailing list.  Is anyone
else having this problem?  Should I try upgrading to -current?

I'd like to take this opportunity to thank the port maintainers for all
their excellent work.
