Does not start on Tails USB sticks.

Does not start on USB sticks.

With BIOS versions A03 06/03/2012 (and A09, A11, and A12)

Error message: `Invalid partition table!`

Workaround (at least with BIOS versions A09, A11, and A12): just hit enter and it will continue with the boot.

This machine does not start from a Tails USB stick: the Linux kernel included in at least Tails 3.11 to 3.13.1, inclusive, does not support the hardware USB controller.

On some computers with a Marvell Avastar 88W8897 Wi-Fi adapter, such as some Microsoft Surface Pro models, Tails fails to connect to Wi-Fi networks.

On some computers with a RTL8723be Wi-Fi adapter, Tails might fail to discover Wi-Fi networks, provide unreliable Wi-Fi connections, or have poor Wi-Fi performance.
