I just read this post on this forum where a user with he exact same chip ID needs to reboot his machine a few times to get the hardware to show up.
There is a thread on the arch bbs from a user having the same chip in a M.2 to PCI setup with issues getting the kernel to see it properly. The solution was to set the power saving setting to off.
What I wonder is how inxi sees the network device and a driver and then ip sees no interface, is the device now also abcent in inxi in the same boot cycle?
I would try to update the firmware and reset the bios to defaults, disable fastboot if there is any option for it.
Please set up some swap space it we will see you here in a few day’s after you have fixed it with the issue of sudden crashes and reboots
