This is a known problem and people are working on it. You said there were panics; please point me at PR's that show them or stop saying it. Also these drivers are completely different and linking them is uninformed. The problem with almost all the reports I've seen is they lack sufficient info to even respond. Understand that most all Intel wireless cards up to the 4965 have issues with firmware mis-design that make developing reliable drivers hard (even more so given Intel's unwillingness in helping anyone not using linux). For example the ipw+iwi drivers try to work around the fact there is no way to scan w/o also initiating an association. But if you try and change the security parameters between scan+associate there are races that can cause the firmware to crash. Most of the complaints I've seen are in this area--people running wpa_supplicant. > > Neither of these are USB adapters. > > rum: Works but panics after a while.

The committer looking after rum has been occupied which may explain the inaction. Sam
