This sounds an awful lot like an FPU-less system running an FPU kernel.
Certain classes of LC040s do not properly allow emulation of F-line traps
and the result is exactly what you're describing; random faults once the
machine boots up.

What version of NetBSD and what Mac and specs?

If it works okay in MacOS, but not NetBSD, that situation is my #1 suspect.

I run NetBSD 1.5.3 on a IIci (mostly for reasons of laziness) and NetBSD
1.6.2 on a LCIII that was turned into a Q605 with a mo'bo' swap (and then
upgraded to a true 68040 _at_ 25MHz), as well as NetBSD/macppc on a 7300 with
a G3/500, so I've got plenty of "MacBSD" boxes here. All of them are
production, and my IIci has had literally years of uptime.
