I am also experiencing the same on a 7840u unit, 2x16Gb Crucial 5600 RAM (CT16G56C46S5.M8G1) & SK Hynix P31 Gold 2TB, swapped AX210. I am here for the ride, really want FW to succeed but I’ve had the same BSODs in similar circumstances per this thread, garbled audio at times and a lovely bug whereby the trackpad doesn’t work at all once the laptop wakes and only a reboot fixes.
Am not piling in for the sake of it, really didn’t expect this to be bulletproof out of the box with new platform and modular approach - but also really want to be able to rely on this machine. I have NOT contacted support, have several machines I can use & jump on them thus far due to time constraints.
Truth is right now if I need to jump on a call or present etc am firing up my old Thinkpad.
If there’s anything needs tested or more info I can provide which might help I am here for that.
