Left my two boxes (one bare-metal, the other a VM) in reboot loops all 
day with your config and haven't hit anything. :(

Do let me know if you're able to trigger this again. Given that the back 
trace you listed doesn't seem to be directly linked to the leapsecond 
related hrtimer changes, I'm wondering if this might be something else.

But if you get any more details, do let me know and I'll try to sort it out.
