[ntp:questions] hardpps difficulty on an ARM-7

I'm currently porting the ppskit version 2.1.1 to an ARM-7 processor using the 2.4.20 kernel. We are using a GPS antenna to receive a pulse, so I believe the pulse to be highly accurate. Unfortunately once I have binded the kernel consumer to the gps 1pps, I keep getting the messages similar to:
hardpps: bad pulse, delta = -39984010 ns
and every 24th bad pulse will output:
hardpps(0.481486004): early pulse, delta = 960006929 ns
instead of the former message.
Any insight to this problem would be greatly appreciated.

PS: Has anyone else out there tried porting this to an ARM7?
