Comment # 3 on bug 973751 from Michael Chang

Gary is on vacation now, and will be back next week.

Generally, it's a good start to check all signatures and pubkeys are in place
before looking deeper to the source code.

To show Mint kernel���s digital signature and certificate.
  pesign -S -i <YOUT_MINT_KERNEL>

To list the enrolled keys in mok database.
  mokutil --list-enrolled

Thanks.
