I think Scott Long was actually asking if you could try to cvsup (or csup) to a date between those two and see if the problem shows there. If you go for, (23 - 12/2) + 12, something like March 17, it would help to narrow what changes could be causing the problem. If you see the problem with a March 17 kernel, you can split the time between March 12 and 17 and try again. Then just keep cutting the search space in half until you can pretty much say "This is the commit that broke things for me." It's not always possible for someone to take the time to do the binary search for the actual commit which broke things for them. But when they can, it really helps the developers. Just cutting it down from 11 days to 5 or 6 days can probably be a big help. -- Scott Lambert KC5MLE Unix SysAdmin lambert@lambertfam.org
