Kernel Messages from the Wifi Card

This wireless device appeared to work fine on the 4.19 kernel, but the current kernel built from GIT causes the Wifi card to be continually restarted, making it unusable. Kernel output attached.

Wireless card shows up under lspci as:
00:14.3 Network controller: Intel Corporation Device 9df0 (rev 30)

I just saw that this has been fixed already, I just need to release the firmware with the fixes. Will do that in a few hours.

Please check with this firmware.
Comment 3 Benjamin Hodgetts 2018-12-29 19:56:46 UTC
Looks fine, no more errors. Only output now is what I'd expect:
