booting ga-j1900n

[george at vagner.com]

i have this gigabyte ga-j1900n motherboard and tried to run 12.0 and 
13-current on it but cannot get it to boot on either version using usb 
memstick or a sdcard formatted with rufus. both 12 and 13 give cannot 
find /boot/entropy when booting MBr if i try EFI boot i get a panic and 
the motherboard reboots.

I was able to boot with 11.0 off usb stick fine .

just thought i would throw this out there.

thanks

george
