RT-BE92U Persistent Thermal Zone Faults

[RicoSuave]

First post here so bear with me if I miss anything. Since purchase, my RT-BE92U has been plagued with the same issues others have posted here. Up until the new firmware version dropped, I was having constant problems with network stability. I am currently running the latest firmware version (3.0.0.6.102_37435) and a lot of the issues seem to have been resolved except for one. Before the firmware update, I was seeing intermittent thermal zone errors in the system log. Since applying the update, I am consistently getting the following errors that appear every 3 seconds exactly:

Jan 4 18:29:52 kernel: read_bpcm_reg_direct_keyhole: Wait for completion failed, devAddr 0x3, offset 24, idx 2
Jan 4 18:29:52 kernel: thermal thermal_zone0: Failed to get RAIL 0 temperature, ret=256
Jan 4 18:29:52 kernel: thermal thermal_zone0: Failed to get temperature, ret=-1
Jan 4 18:29:52 kernel: thermal thermal_zone0: failed to read out thermal zone (-1)

On occasion, the errors coincide with a drastic decrease in wireless network performance. Under normal conditions, when connected to the 6GHz network, my wireless network download speed averages around 1100Mbps. This will drop to a nearly unusable 2-3Mbps. The 2.5GHz and 5GHz networks also see a decrease in speed to around the same 2-3Mbps. Wired clients seem unaffected. Once I perform a hard reset to the router, it seems to correct the speed issue for a while, but the thermal zone errors continue to persist. This seems to happen anywhere from once a week, to every day. Performing a hard reset isn't something I want to nor should have to keep doing to correct the issue every time it happens. Please let me know if there is anything else I can do to stop this from happening. I am getting very close to returning this router and exchanging it for a different brand. Thanks.

Want to chime in that I am having the same behavior on my RT-BE92U with the reported repeating thermal error in the system log.  I have submitted through the feedback tab though the router management webpage.  Core 4 on system status is constantly bouncing and RAM utilization is basically pegged at 73% with minimal traffic.
