Sansa Fuze V2 Startup Issues
Chronon:
It is possible that there is an undocumented hardware revision. At least this might explain why some units seem to have a problem booting and others have no problems with the same firmware.
saratoga already asked people to find which revision introduced the problem. This would be a great place to start.
Matoridi:
Well, I was not doing daily updates before. It all worked with the previous 3.6 release, although the radio was not always functional ...
Frankly, I'm beginning to wonder whether there is a hardware defect related to this problem... The sansa firmeware also has problems with the radio in my case.
AlexP:
This is what stable means:

And yes, it meets those criteria. The vast majority of fuzes do not have the problem yours has, and none of the developers with a fuze has this problem. This makes it rather hard to fix. Someone with a problem fuze needs to do a binary search to find which revision introduced the problem, without this nothing can be done.
Matoridi:
I'd like to help, but I have no idea how to proceed to do a binary search...
Meanwhile I am investigating the possible hardware problem. I'll comment here as things develop.
AlexP:
A binary search is the quickest way to find the problem revision, as described here: http://en.wikipedia.org/wiki/Binary_search_algorithm
Basically if you know that revision x works and revision z doesn't, then try revision y half way between them. If that one works, now try half way between y and z. Very quickly you home in on the problem revision. To do this you need a build environment set up so you can build old versions of Rockbox.
Until someone with the problem does this, it won't/can't be fixed.
