Well, Xen is not a typical thing to run on embbeded hardware, but I
did not check the configs.

It seems Linus is having power problems:

Sadly, the power at my house is still entirely out, although cell
service
has now been fixed so at least I can read some email without walking
outside.

But with no power for my laptop or workstation, I won't be starting
the
merge window until power is back more widely in they Portland area.

My neighborhood is likely not a priority, so it very possibly will be
a few
more days (so far without power since Sunday evening).

Even the local highway 43 (ok, not a big highway, but still) is still
closed down two days later due to downed trees.
