Intel wifi issues after updating from 5.5.6 to 5.5.7

Network Manager is toggling between "device not managed" and "device not ready". This makes sense, as when I run ip link repeatedly I can see the device being added and removed:

[root@groot ~]# ip link | grep wlp2s0
328: wlp2s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
[root@groot ~]# ip link | grep wlp2s0
329: wlp2s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
[root@groot ~]# ip link | grep wlp2s0
[root@groot ~]# ip link | grep wlp2s0
336: wlp2s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000

If I try to set the device up I get one of two errors:

[root@groot ~]# ip link set wlp2s0 up
Cannot find device "wlp2s0"
[root@groot ~]# ip link set wlp2s0 up
RTNETLINK answers: Input/output error

I've restarted the usual services (NM, wpa_supplicant), and checked that there weren't other services that might be conflicting with NM).

Any other thoughts?

What is that wlp2s0 device - what Intel model (lspci -nnk) ?

Downgrading an update further to 5.4.8 has resolved the wifi issue. I don't know what allowed 5.5.6 to run successfully for a week, but maybe this is just the intel wifi issue people have been having with 5.5+ kernels.

(actually, now that I think about it, it wouldn't be terribly unlikely for me to have forgotten to reboot after the 5.5.6 update. Maybe I've been running 5.4.8 this whole time >.< )

The system's journal will show when the system was rebooted and also the kernel messages for the issue.

You're right, and the logs do confirm that I hadn't rebooted yet after updating to 5.5.6

I'll keep working on the wifi issue, but since this now appears to be just another instance of a known issue I'm going to post any results on the other thread.
