I don't have a setup to build there, I am trying RelEng kernels.
I could use those to bisect - but I have worse news. Even NetBSD 8 
release is actually unreliable. So it did work, but I tried again and 
got a black screen... so it is not a repeatable reference.
Darn :) Would have made things easier.

As you say - it might make sense to work on the ThinkPad which spits out 
at least a trace, the invalid TSS.

Any further ideas?

If somebody has a specific clue for a driver to disable on any of these 
three test systems, just tell me!
