Summary	0003080: airodump-ng crashes with Illegal instruction message
Description	I'm running the rolling update Kali Linux on a 2012 Dell Latitude E6400 laptop. After updating the aircrack-ng package to 1:1.2-0~rc4-0kali1 the airodump-ng binary always crashes/exits with the message "Illegal instruction" and nothing else. The default X11 terminal also loses the cursor (i.e. it goes transparent) until the "reset" command is given. This happens both with the on-board Intel Corporation WiFi Link 5100 wifi interface, or a TP-LINK TL-WN722N USB adapter with an Atheros chipset. Some internet searching yielded an aircrack-ng bug that appears similar, but is very old and may not be the same issue: http://trac.aircrack-ng.org/ticket/154 Dumps of /proc/cpuinfo and uname -a are included in the "Additional Information" section.
Steps To Reproduce	sudo apt-get update sudo apt-get upgrade -y; sudo apt-get dist-upgrade -y sudo airmon-ng check kill sudo airmon-ng start wlan0 sudo airodump-ng wlan0mon

rhertzog 2016-02-19 09:36 administrator ~0004731	It looks like aircrack-ng got some autoconfiguration logic enabling usage of some CPU features which are not used by the default compiler. So the package uses AVX instructions and you don't have those. We will fix the package to not rely on newer CPU features.

sbrun 2016-02-19 13:10 manager ~0004734	The new version 1:1.2-0~rc4-0kali3 should fix this. It will be available in the next hours.

jonathanyhsu 2016-02-19 15:29 reporter ~0004740	Thanks; I updated aircrack-ng to 1:1.2-0~rc4-0kali3 and the issue is resolved and no longer present.
