NetBSD/hpcmips userland crashes (Re: IBM Workpad z50 dmesg collection)

Hi -

I'm aware it's been almost two years, but I've finally put in a 
couple of hours to go through a number of the test kernels you 
compiled back then...

This seems to have started pretty early on after the 2016-07-01 
kernel: That's the last one i tried that shows no problem.

Both 2016-07-01 and 2016-08-01 hang after this message in the boot 
process:

 > pid 1(init): ABI set to O32 (e_flags=0x1007)

2016-10-01 boots to multiuser, but ntpdate is the first program 
to crash:

Later, virecover has to be stopped with ^C to reach a login prompt.

2016-11-01 and 2016-12-01 are missing, and then 2017-01-01 errors 
out immediately and drops to a single-user shell.

I can provide dmesg / boot logs if it helps any, but also I' fully 
understand if you don't want to put any more work into this after 
I didn't do anything for all this time.
