Is it in a location that's known to have a usable GPS signal? I found that in 
some locations my Garmin sometimes couldn't get a fix either. If you can do 
it side by side testing would be useful.

Have you tried without the SD card present? While the kernel you have gives 
reasonable performance with the SD present in my experience, testing without 
SD would help to narrow things down a bit.

Do you have access to an external antenna?
