This hardware / OS connection problem is getting really annoying for
everyone and this pattern is repeating itself since several years. It is
time we fix it properly.

The first solution looks hackish from my POV. The second approach looks

flagging approach proposed by Mark [3].

I added Arnd in Cc in order to have its opinion.
