Hi all,

I'am using iwlwifi in the 13.1R on my ThinkPad X1 Nano with AX201.
It works well. I'm happy. I'd like to thank you here.

But, it stuck occasionally.
I could not find the cause. Perhaps, high load?
To recover the network, I need to restart it by using /etc/rc.d/netif.
For the note, I put dmesg below.

Best,
Takashi
