This makes no sense at all. I just added a one-liner in probe_board(),
reading the cookie twice after each other.
int err = check_cookie(board);
replaced with:
check_cookie(board);
int err = check_cookie(board);
Test: the clock is at 32MHz in _both_ instances. Remove that line and
the clock is 50MHz again. Argggh... Maybe the compiler is doing funny
stuff. Could be a missing volatile.
It is too late to dig into this now. I have to sleep on this one.
