The frigging ux305ua! Oh hell no I know what issue you are talking about since I had to bisect the kernel to find it. The bios had non standard vbt handling (to put it mildly) and the newer implementatiin which didn't have defaults set and relied on the hardware simply stopped booting. Also the keyboard backlight needed dsdt fixed or acpi parameter to work correctly and the touchpad kinda worked randomly (the keys). It was a great big hack to get everything working and even thought it's a light kinda nice looking laptop I wouldn't recommend it to anyone. Additional disclaimer: everything seems to work fine with the newest kernel revision
