Public bug reported:

My computer's wireless card activates by using a switch. When I turn the
switch on to use wireless networks, the computer slows down *very*
noticeably for a few seconds (two or three) and goes back to normal. The
cursor freezes or moves very slowly, and if there is music playing, it
stutters (which is annoying). That doesn't happen when I turn the switch
off, it only happens when I turn the switch on. The card is an "Intel
PRO/Wireless 4965 AG or AGN Network Connection", using the iwl4965
driver. I'm having this problem long time ago, but I hadn't reported
this any sooner because it didn't seem so annoying as it is now.

The info about my computer is as follows:

- Computer: HP Pavilion dv6871us

- 'lsb_release -rd' output: 
Description:    Ubuntu 8.04.2
Release:        8.04

- 'uname -a' output:

- 'dmesg' output (taken after turning on the computer and the wireless
switch), 'lspci' output, 'modinfo iwl4965' output, 'iwconfig wlan0'
output: dmesg-lspci-modinfo_iwl4965-iwconfig_wlan0.log (attached)
