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.

PR #?  Unfortunately my rum card seems to have vanished.  The committer 
looking after rum has been occupied which may explain the inaction.
