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
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

Yes, after the first time it happened (with the stock 5.10.30 kernel)
I updated the rtw88 firmware from git, it happened again. Then i used
the modules from the above location (which also match the git
firmware), and the behaviour persists.
