[Bug 44601] Re: ipw3945: wireless uses a lot of of resources since system update

[Samir van de Sand]

** Description changed:

  I own a Intel Centrino Duo laptop with Intel Pro Wireless 3945 network
- card. (using kernel 2.6.15-22-686)
+ card and running Ubuntu Dapper on it. (using kernel 2.6.15-22-686)
  
  I had no problems with those wireless drivers until I made an dist-upgrade on the 12th or 13th May.
  Since then every few minutes, those wireless drivers start taking a lot of system resources for about 30 seconds (music hangs, mouse goes crazy ...), even though I'm not connected to any wireless network !
  If I type "top" in console in those 30 seconds in looks kinda like this:
  Tasks: 108 total,  24 running,  84 sleeping,   0 stopped,   0 zombie
  Cpu(s):  2.7% us, 10.1% sy,  0.0% ni, 84.6% id,  0.0% wa,  1.3% hi,  1.3% si
