It's after *any* suspend.
Even after a clean boot, if I suspend before doing anything else, GPS doesn't

That's the only difference I see between your installation and mine.
I flashed a new image on NAND when SHR jumped to 2.6.32. It was then when GPS
started to fail.

I have tried it, and it doesn't help at all.
I have also tried to boot FR without SD, without SIM, and without both (I'm
currently having problems with my uSD).
No sucess at all. I have also tried to clean AGPS data. I have waited for
about 15 minutes for a fix, and I couln't get even time from GPS satellites.
After a suspend, my GPS doesn't work at all, no matter what I do :(

That's what I'm doing. I'm not letting FR suspend, forbidding it from quick
settings, but battery drains very quickly.
Other solution could be boot FR every time I needed to track something, but
it's not so practical ;)
