| I tried the kernel too, but it didn't help. Didn't get any fixes in 3
| minutes when having SD card in (not in use, ie. maps not there).
| Removed the SD card and got a TTFF in 34 seconds.
Two points about testing it:
~ - order of tests can matter. If you get a "good" test first, it seems
the requirements for next test can be relaxed by GPS chip and we don't
really test it then.
~ - patch only helps if SD Card is not accessed. I read a thread
yesterday in devel list about some ASU / Qtopia component spamming SD
Card after start up.
