EC no response on HP laptop

[Daniel Eastwood]

Hello everyone,
I have just got a new laptop (HP 14-dq0052dx) and trying to install FB 14.0-release. But during installation and after booting into newly installed system I got
acpi_ec0: EcCommand: no response to 0x84 acpi_ec0: EcCommand: no response to 0x84 acpi_ec0: GPE query failed: AE_NO_HARDWARE_RESPONSE
repeatedly after an uncertain period of time. Adding the line debug.acpi.ec.burst=1 or debug.acpi.ec.timeout=1000 in /boot/loader.conf won't fix this problem.
What went wrong?

sysctl kern.consmute=1
while you check if there is a BIOS update available that could solve the problem

I have installed the update, the problem could not be solved.

I wonder if there is a method to pin out what is going on. I tried sysctl hw.acpi.verbose=1, though noting useful is given, seems EC is still functioning, for I can get lid switch events.
