The very short answer is that new hardware tends to require new software.

That makes sense - although I thought that this card had been around for a while.

I looked at this question before posting here http://unix.stackexchange.com/questions/207855 (from June last year)

Followed all the leads there but my drivers were already as recent as that.

Try upgrading to new kernel/Xorg driver/mesa. (You might want to try out using a live cd/usb first).

I did try kernel 4 (via backports) but that broke other things, and it did not fix the problem.

You might also need new microcode updates, I'm not sure if they are pushed for the updates for jessie.

Don that now, by using apt-get install intel-microcode

The same thing goes for bug reports, if you can't reproduce the problem with the latest software they tend to not be very interested.

What same thing? I'm just trying to figure out what causes this hanging / if anyone knows a solution.

It may not be a bug -- if I can solve it by using backports, switching to testing or installing proprietary drivers then I'm more than happy to give it a go :)
