I can confirm that firmware 3.0.0.4.382.15850 for RT-AC88U is not working well. I also have excessive log entries (sometimes multiple ones at once, multiple times per minute). I also found that both 2.4GHz and 5GHz WI-FI signals would suddenly stop working, and only a reboot would fix it, and then only temporarily. Other times, I was unable to connect to the Internet, with the WAN LED turning red. And the ASUS UI would sometimes slow down to a crawl, taking about 10 seconds to update a screen. Prior to installing I did reset NVRAM, but the problems persisted. I used the recovery tool to go back to the previous firmware, which is working well.
