Subject: Re: [ipw3945-devel] iwl3945 in 2.6.24-rc1 dies under load

actuually iwl3945-rs does more than performance, it will force some 
rules that could be causing this assert like transferring rate 
restriction on broadcast and management frame, The could new this is 
SYSASSERT which we can trace and find what causing it.
