Yepp, this is the "problem". The TCB-clock is not found in at91_ipipe_time.c:
the setup-code looks for "at91_tc0", but there is only a "at91_tcb" clock.
Below is a patch which should avoid this problem. The patch was created on base
of linux-2.6.24 + adoes-ipipe-2.6.24-arm-1.9.00.
Thanks for your hint,
Karsten.
