Awesome, thanks for the input. I've included both of your suggestions in
version I'm about to upload.
There remains a more fundamental problem with kernels 3.10 and 3.11, they both
contain a deadlock in the timekeeping subsystem. It is fixed by commit
7bd36014460f793c19e7d6c94dab67b0afcfcb7f "timekeeping: Fix HRTICK related
deadlock from ntp lock changes".
Unfortunately, lttng-modules is not compatible with the now-default sid kernel.
The package will install, but DKMS will fail to build, with an error similar to
the above in make.log.
It sorta sucks, but I'm not sure of a better way of handling it. If you have
suggestions I'm all ears.
