Hi,
I noticed this warning on 5.16, recompiled to 5.19 and still saw it.
Its happening on a UML kernel running many tests if that makes a
difference. It will happen several times during a full test run, warn
many times >60, then stop for a bit and repeat.

Probably a separate issue, but I also noticed this print on 5.19:
[ 1054.390000] wlan107: authenticate with 02:00:00:00:f1:00
[ 1054.390000] wlan107: bad VHT capabilities, disabling VHT
[ 1054.390000] wlan107: Invalid HE elem, Disable HE
[ 1054.390000] wlan107: 80 MHz not supported, disabling VHT
I don't think its related since I don't see this on 5.16, but still see
the crash.
Thanks,
James
