HP with Raven Ridge has no Wifi on current kernel #84

On the latest update, to kernel 5.3.11-19 wifi seems to have stopped working.

I wasn't sure the best way to check the wifi module, but this output is the same on this kernel and the previous version where it worked:

$ ls /sys/class/net/wlp3s0/device/driver/module/drivers
pci:rtw_pci

However in gnome network settings no wifi networks show up and I cannot connect.

The main thing I'm unsure about at the moment is which extra info would be useful and where to get it from.

Running rfkill was showing an extra interface:

ID TYPE      DEVICE       SOFT      HARD
 0 wlan      hp-wifi   blocked   blocked
 1 wlan      phy0    unblocked unblocked
 2 bluetooth hci0    unblocked unblocked

Compared to older kernels where this was working

ID TYPE      DEVICE       SOFT      HARD
 0 wlan      phy0    unblocked unblocked
 1 bluetooth hci0    unblocked unblocked

The module for which showed up in lsmod

$ sudo lsmod
...[snipped]
wmi                    28672  2 hp_wmi,wmi_bmof

Removing the extra interface got wifi working: sudo rmmod hp_wmi.

I blacklisted the module by creating /etc/modprobe/blacklist-wifi.conf with this content:

blacklist-wifi.conf

Cheers :)
