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 (it may have been
fixed in another version between 3.4 and 3.9, but I did not test those,
so I don't know for sure).
[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.
