Hello, I am using: compat-wireless-2012-04-04 I am doing such test: - insmod compat.ko - insmod cfg80211.ko - insmod mac80211.ko After that: - rmmod mac80211 And have PC freeze. Linux uw000950 2.6.35-32-generic #67~lucid1-Ubuntu SMP Tue Mar 6 17:48:20 UTC 2012 x86_64 GNU/Linux Any idea what could be wrong, how to debug in case of such freeze?
