The wifi device had issues with kernel versions 3.2 and 3.4, which are the only two other versions tested. It could connect, but the connection was lost frequently. This issue is fixed in version 3.9.
[p]
For kernel versions from 3.7 to at least 3.9, make sure to build the modules for the webcam and wifi devices. When running make menuconfig, check the following:[/p]

There was an issue of not being able to shut down. When shutting down, the system would restart itself. Here's a fix I found on a blog (http://www.pbehnke.com/main/node/11):
[enum]
[*] Create an init script in /etc/init.d (Example: create a file named /etc/init.d/haltusbpower)[/*]
[*] Put the following in the script:
[code]#! /bin/bash
#
# haltusbpower init script
#
# chkconfig: 345 99 20
# description: A script to act as a workaround for the bug in the runtime power management module, which causes my acer aspire v5-571 laptop to restart after shutting down.
#
### BEGIN INIT INFO
# Provides: haltusbpower
# Default-Stop: 0 1 3 5
# Short-Description: Halt USB Powersave mode
# Description: A script to halt usb power control.
### END INIT INFO
# Source function library.
. /etc/init.d/functions
# Bus list for the runtime power management module.
buslist="usb"
# See how we were called.
case "$1" in
start)
echo "USB bug fix active"
#no-op on startup
;;
stop)
echo "Turning off USB Power Control"
for bus in $buslist; do
for i in /sys/bus/$bus/devices/*/power/control; do
echo on > $i
done
done
;;
*)
echo "Usage: /etc/init.d/haltusbpower {start|stop}"
exit 1
;;
esac
exit 0[/code][/*][/p]
[*] Create a symbolic link in /etc/rc0.d to the script you created in the previous step. [p]Example:
[code]ln -s /etc/init.d/haltusbpower /etc/rc0.d/haltusbpower[/code][/*][/p]
[/enum]
One issue remains: I cannot change the backlight brightness.
