Everything works except keyboard backlight. But this can be reenabled by calling:
sudo sh -c ‘echo 1 > /sys/devices/platform/sony-laptop/kbd_backlight’

WIFI doesn’t work as it should anymore, it’s incredibly slow!
This worked for me:
sudo ifconfig wlan0 down
sudo rmmod -f iwlagn
sudo modprobe iwlagn swcrypto=1
sudo ifconfig wlan0 up
It disabled hardware encryption of the WIFI chip, which is broken in the current driver. To make these changes static just run the following command:
sudo sh -c ‘echo “options iwlagn swcrypto=1” > /etc/modprobe.d/iwlagn.conf’
