Also, is this an SMP kernel by any chance? I've just spent several days trying to fix a similar problem with a 4.3 SMP installation. The clock would run correctly when booted into non-SMP kernel. It would also run correctly if I rebooted it once I had observed it running fast. If the machine was coldstarted once more then the problem would re-occur - very strange behaviour! I think I've got it controlled now by adding 'noapic' to the kernel parameters. I did quite a bit of googling whilst trying to work out what was wrong and it seems there is a bug with SMP kernels which should be fixed in 2.6.14 if I remember correctly. However, if you're not running an SMP kernel then this is all irrelevant so I'll shut up! -- Mark Whidby Faculty of Engineering and Physical Sciences
