Hi Aaron~ I have attached the debug info you requested for #16.
This time I re-blacklisted r8822be driver in blacklist.conf and removed rtwpci from blacklist.conf, rebuilt initrd, rebooted, and used the rtw88.debug_mask=0x3ff option in linux cmdline in GRUB. As expected, wifi is not working when only rtw88 driver is active (and r8822be is inactive). Next I will try with the mainline kernel.
