[MinnowBoard] Firmware hang

[Sjoerd Simons]

Hey,

I've been having issues with some of the minnowboard max boards in our
test lab for a while where at times they never finished post.
Reflashing the flash seemed to help for a while, until the issues came
back again. With the debug version of the firmware the last few lines
are:

Gpio_S5_4 value is 0x3
Gpio_S5_17 value is 0x3
Firmware Volume for Variable Store is corrupted
Firmware Volume for Variable Store is corrupted

ASSERT_EFI_ERROR (Status = Not Found)
ASSERT m:\Vlv2TbltDevicePkg\PlatformInitPei\PlatformEarlyInit.c(213): !EFI_ERROR (Status)


A full log can be found here:

Any ideas?
