on some laptops, the kernel doesn't deactivate the usb controller, resulting in a black screen and forcing to a hard reset. the laptops are: * Acer Aspire 5750-6690 * Asus EEEPC 1000H * Asus B53F * Asus K52F * Asus K72JR * Asus N53J * Asus N73JG * Asus P31F * Asus U35JC and U36JC * Asus U50F * Asus X53E-SX107V * Averatec 2200 * Dell E4300 * Dell E6400 * Dell Studio * HP EliteBook * HP Envy 17 * HP Compaq * IBM T410s * Lenovo ThinkPad SL500 * Lenovo 3000 Y410 * Sony Vaio VPC-F115FM VPC-F13S1E * Sony Vaio WGN-FW235J * Toshiba Satellite U500-1DV known workaround: http://ubuntuforums.org/showpost.php?p=9744970&postcount=19
Please get people to retest with a current kernel commit 151b61284776be2d6f02d48c23c3625678960b97 should have fixed this. It would be useful to know which machines are fixed and if any are not.
