I have a 9310 32gb model with the ax500. With a 5.17 kernel and the WLAN.HST.1.0.1-05266-QCAHSTSWPLZ_V2_TO_X86-1 ath11k firmware, the machine has been flawless. Well maybe not the fingerprint reader.. i installed some updates and that broke but I never really used it so I haven't bothered trying to fix it.

Oh and make sure you configure the nvme to AHCI in the bios. The intel raid stuff is trash and causes major battery / suspend issues in my experience.
