Yes, unfortunately kernels 3.10 and 3.11 have a critical bug in the timekeeping subsystem that these modules can expose. Even more unfortunately, 3.10 is currently the default kernel in sid. I'm not sure how better to handle this, it seems wrong to conflict against these versions of linux-image - just because you have them installed does not mean you don't have other kernels that you wish to use with lttng-modules-dkms. Perhaps there is a way to blacklist them in DKMS and only build against safe kernel versions - I'll have to look into this more. If you have additional suggestions, I'm open to those as well.
