I've never tried booting from a USB stick, but perhaps you need to set the 
boot flag on the partition you're trying to boot from?

# echo "a
1
w
" | fdisk /dev/sda

Would mark /dev/sda1 (assuming your Linux setup is on the first partition) as 
bootable.

One of the items from your log might shed light on this:
        [110.420000] FAT : invalid media value (0x06)

What format is the partition you're trying to boot from?
