I was using the rtw88 on (lspci: Realtek. RTL8822CE 802.11ac PCIe on a Lenovo Thinkbook) fairly normally on gentoo (kernel 5.10.30) with netifrc scripts. Recently I tried to move the scripts to networkmanager connection files. 1. With NM the WPA-PSK connection to my AP (dlink router - india) keeps dropping (citing a CLASS2_FRAME_FROM_NONAUTH_STA error) 2. With a specific connection file - if I activate the connection with nmcli conn activate the kernel apparently terminates all processes on the system except the NetworkManager process. (For added fun this crashes the drm video + keyboard if Xorg is running requiring a powercycle) How could this behaviour (all tasks being terminated) possibly happen? Is it b related specifically to the rtw88 module? Have you heard of anything like this before? [Other Issues I had were 3. occasional RIPs "purge skb(s) not reported by firmware" 4. RIPs when I try to run kismet which may be related to: 5. Usually I see only 2-3 APs from this card on linux. On a b43 driver older laptop I can usually see 10-15 APs at the same time. I suspect the kismet RIPS happen when processing these other APs ] In any case I'm intrigued by the (2) kernel repeatably killing off all my processes when nmcli fires up. This is a bit hard to debug as there is nothing helpful in dmesg afaict. (and syslog exits early) How is this even possible. (Offhand I can't spot where nm is calling killall)
