Re: [Libreboot] Thinkpad x200 with Libreboot 20160818: problem booting from USB

[persmule]

   Hi Marcel,
   According to my experience, slower usb flash drives work stabler.
   It may be due to libreboot using a slower but simpler mode to operate
   USB, and some newer and faster usb drives work poor under this mode,
   while operating systems can use faster and more complex mode.
   I have prepared a [1]SanDisk Cruzer Micro 4GB and a [2]ADATA C906 4GB,
   both of which work very stable, to hold bootable images for my
   libreboot computers, and ADATA C906 is a bit faster.

     Can you try another USB drive? Not all drives work reliably in the
     GRUB payload.
