I have this WLAN / Bluetooth adapter under Archlinux run (with kernel 3.19.2). The card has been recognized out-of-the-box (should not that be the case, the installation of the package "linux-firmware" helps (the name may vary depending Distribution vary slightly)). Bluetooth and WLAN (2.4 and 5 GHz) function. However, I had (in which was removed with a modified BIOS WLAN whitelist) on my Lenovo Y570 the problem, that the computer extremely slow booted: The Power-On Self-Test and Loading Grub2 took a long time after the boot process continued with the usual speed. Remedy managed taping of PIN 51 with package tape.
WLAN and Bluetooth continue to work (even after a suspend to disk / RAM) and the machine boots again accustomed quickly.
