Hi,
I'm getting the following panic under NetBSD 3.0_BETA while building the
3.0_BETA userland under a 2.0 userland.

panic: kernel diagnostic assertion "emsr & PSL_EE" failed: file "/amd/quanta/roo
t/export/netbsd/netbsd-3/src/sys/arch/macppc/macppc/extintr.c", line 811

I'm using NFS exported sources, as you can see.

Also, I'm getting some gcc (cc1 and ld) segmentation faults.

May these two problems be somewhat related to memory problems or CPU problems
or has anyone already saw it ?

P.S.: This has nothing to do with CPU reboot as in

Thanks.
