It's
x86_64machine and I have GPS w/ PPS (Garmin 18x LVC) connected via serial, without it kernel boots/works fine. Also no issues with GPS connected, but PPS disabled (by removing pps_core.ko module). If I'm connecting GPS w/ PPS to already booted machine — cursor on the display stops blinking and I cannot input anything, but I still can switch between VTs using Ctrl-Fx and keyboard LEDs are blinking when I'm pressing Num/Caps Lock keys.
Ok, you have a problem fixed by this commit:

pps: Use pps_lookup_dev to reduce ldisc coupling
I think this should go to stable-3.8 with its prerequisity:
