Can I suggest you consider FreeBSD ? You can use the TIMER4-7 input pins
as PPS input for a better PPS. See the following URL for details:
If I recall correctly, the patch is in the FreeBSD 10 snapshots for the
Beaglebone, so you don't need to apply it, but you will need to enable
PPS and ensure one of the four TIMER pins is set to input in the DTS
