sorry, no, i accidentally posted that here instead of the intended place
as mentioned on irc, just send me your board
i will investigate it directly. i think this is just your board. i haven't seen this with any other x200t. i will pay for your shipping cost to send the board

It appears this issue was due to bad microcode.
Sorry for the confusion.
