Public bug reported:
On RPI4, if you set up netplan to use wifi, and plug in a usb3 storage
device to one of the 2x usb3 ports (the ones closest to the ethernet
port), wifi will sudden stop working. If you unplug the usb stick while
running a ping, it will usually start working again almost
Po-Hsu Lin, I accidentally changed this to "Fix Released". Not sure if
that affects everyone or just my view, but I cannot change it back.
Please correct the status with my apologies for changing the status.

IMPORTANT UPDATE (I guess):
I discovered that using linux-image-5.3.0-18-generic bluetooth works,
while with 5.3.0.29.33 it doesn't!

I attempted to bisect this, using the following process:
- Run the kernel-build-reboot-loop test on 3 machines in parallel
I used 2 CRB1S systems (anuchin, bestovius) and 1 R120-T33 (seidel)
- If any machine crashes w/ the parity error message, consider it failed
- If all machines
I reproduced the problem also with 7.2.7 upstream. It worked with master
branch however. I haven't bisected it to the specific commit, as 7.2.8
should be released soon, and I'll push to get this in focal.
Thanks.
Cascardo.
