I have just tested that on at91rm9200-ek:
- revert the revert (!)
- experience the crash
- then apply the v2 patch
- and finally see it working nicely!

Thanks a lot for having corrected this. Now, do you want that I stack 
this revert-of-revert on the AT91 git tree or you are able to apply it 
through the clock git tree together with the patch that is fixing the 
issue (it may prevent synchronization difficulties)? (BTW, I do not see 
it yet in "next").

Anyway, if it is required, you can add my:
