With the latest two kernels (2.15.19 and 2.15.20), when I start jack using qjackctl, it immediately starts reporting xruns at the rate of about 10 per second - and this is with no applications running at all. I'm not sure about how to go about debugging this.

It's possible that they used to use realtime-lsm and recently switched
to the rlimit approach (although, shouldn't JACK bomb out if started
with -R and realtime scheduling is unavailable, rather than failing
silently?).
Try adding this to the end of /etc/security/limits.conf:
* rtprio hard 99
* nice hard -20
Then reboot and try it again.
If it still fails please post the JACK output
