Bug Description
This seems to be a return of an existing bug, in newer hardware and microcode versions.
Wireless card: Intel Corporation Wireless 8265 / 8275 [8086:24fd] (rev 78)
Firmware version: 34.0.1
Description: Ubuntu 18.04.1 LTS
Frequent errors as soon as I connect to wifi:
Microcode SW error detected. Restarting 0x2000000.
Expected to happen: Great and stable wifi like a couple of weeks ago
What happens: very slow, intermittent internet access, lots of ping loss
Found a suggestion of a workaround: adding these lines to /etc/NetworkMan
[device]
wifi.scan-
These lines were already there, not added by me.
