That's what happens if I switch to the old one ... haven't seem one of those on iwm(4) in ages ...  *sigh*  That's an LQ command in RUN state.

I guess if anyone it's me who might look into this ..

Crashed iwm(4) again in a hotel but this time it couldn't even get the errlog.
No idea what changed there but no longer helpful at all.
Someone might want to check how/when this can happen.

iwm0: device timeout
iwm0: dumping device error log
iwm0: errlog not found, skipping


Also (re-)assigning to wireless.

Close it;  overcome by events but good to have it for reference.
