Bug Description
With my Lenovo IdeaPad S10e, after updating to 14.10 from 14.04 the WLAN does not work anymore - the driver seems to be loaded since the hardware light flashes blue/purple, but the device is unable to connect to any WLAN. dmesg shows:
[ 1253.135793] ERROR @wl_dev_intvar_get : error (-1)
