I wanted to benchmark some operations there, but as you heard its a bit
paint to bring it up after kernel upgrades, so I still did not have the
opportunity to do something and see if -rt really matters in my case.

Might be separate drivers but we have similar problems after upgrades from
wheezy to jessie.
I think OP might have one of my 2 cases (systemd vs init or kernel). of
course it could be anything.
I have 2 small Geod machines that I need to upgrade as well and I'll plan a
weekend for that. There for example no recent kernel runs - the latest
working is 2.6.26. It took me about a month of investigation - but its
doing what it should since 2007. I think the time spent has paid off
already.
