Note that the system counter is only guaranteed to be at least 56 bit wide (see DDI0487B.a G5.1.2), and I seem to remember that X-Gene only has the minimum. This could explain why setting the comparator to a value greater than (2^56 - 1) leads to a firing timer (the comparator appears to be in the past). Thanks, M. -- Jazz is not dead.
