This seems to be a DVM device (iwldvm).  What is the exact device
model? And you have never noticed this problem before?

Unfortunately this is a very old device and we don't support it
actively anymore.  Hopefully this will turn out to be a trivial fix in
the driver side, so we can get it solved for you.

The best way to track this is to report it in
https://bugzilla.kernel.org.
