I am seeing some weird CPU usage issues after upgrading to 388 from 386.7_2 on my Asus RT-AX56U.
I have tried 388.1, 388.2 Beta and now 388.2, all resulting in the same outcome.
Issues:
1. Only 3 out of 4 CPU cores of the router is utilized. 4th core is always idle.
2. Higher than usual CPU usage on 388 firmwares compared to 386.7_2 constantly, even on idle. The "sysstate" process using up quite a lot of CPU time.

I have tried:
1. Dirty flashing from 386.7_2 to the 388 series firmwares.
2. Factory reset on 386.7_2, then flashing to 388 series firmwares.
3. Factory reset on 388 series firmwares after upgrading from 386.7_2.
All outcome are the same as above.
Going back to 386.7_2 also always resolves the problem.
Appreciate if anyone can help to shed some light on the behaviours of the router above.
Thanks!
