Nobody every figured it out if the issue is in the kernel or in the gpsd

esr spent various hours on it and so I've done.
If you have a trivial and reproducible way to trigger the issue, please
show me. So far it happens just random.

Don't forget that we had write_pad for linux for some time before. Its

the cpu speed got faster these days.
