I just put 4.10 on a PCEngines WRAP board, older model, that is showing the system clock incrementing by 10 seconds every second. It did the same on 4.6. NTP is setup, but I am dropping a 5GHZ link quite often and watching this clock advance at a tremendous pace. The system believes it has been up for 5 days, I rebooted last night.

Any ideas? This is one of my backhaul links, and it is creating quite the problem.

Thank you.

BIOS Firmware upgrade?..

This sounds like what happened with 3.x when you loaded the wireless test package.

disable the nstreme if it is possible.
and try to use RouterOS v5.0beta3 when it is released and then play with the multi-cpu option. We hope to release v5.0beta3 soon.
