ELF - panic on installworld

[Wolfgang Zenker]

Hi,

I'm trying to run installworld using 11-STABLE on an Ubiquity Edge
Router Lite (mips64, 2 cores, 512 MB Ram). Unfortunately I haven't
managed to finish the installworld yet, I always get a
panic: kernel stack overflow - trapframe at 0xffffffff80917eb0
in slightly different places during the installworld. Of the 4 panics I
have seen on the serial console, 3 had the trapframe at 0xffffffff80917eb0
and one at 0xffffffff80915eb0
/usr/src and /usr/obj are nfs-mounted, and I have configured almost 2 GB
of swap. The build was done in a Qemu environment.

Any hints how to proceed from here?
