I'm currently busy with other things so the update in shim may be delayed
for a while.

shim and grub2 are using the openssl lib independent from the one in firmware,
so it surprised me the openssl update patches broke the bootloaders. I just
tested OVMF R17650 with openSUSE 13.2 and everything went well. The shim we
use in openSUSE 13.2 is 0.7 + a series of patches (most of them are upstream
patches). Hope this could narrow down the issue.
