Really? And I thought that was the least significant bit...

I had a lucky guess among the 2000+ lines of diff output with
which I started: CONFIG_PM_RUNTIME makes the difference.
If it's on, the kernel can freeze.

I'll have to add the debug output you asked for tomorrow,
didn't expect to succeed so soon.

Should I put the statements into the 3.17 kernel, or should I
try to compile a 4.2 without CONFIG_PM_RUNTIME instead? And
would you like the output of a freezing or non-freezing kernel
first? I'll only be able to try out one tomorrow, the rest
will follow a day or two later.

cheers and thanks,
  Roland
