The new stacktrace is below.  It doesn't look to me like there is more than
one thread.

I should also point out that I was having some trouble reproducing this.
Yesterday the crashes happened reliably after resuming, no matter whether the
laptop was docked or not, today I can only reproduce it when suspending in
undocked state and resuming in docked state.  So maybe it has something to do
with docking after all.  Oh, and when I'm talking about "undocked", that
implies "on battary" while "docked" implies "power supply connected".

Thanks,
Jö.
