Bug#928300: secure boot via removable media path unavailable

[Timo van Roermund <timo@van-roermund.nl>]

Dear Chris, Steve,

Was there any further follow-up on this issue?

It seems that I've got pretty much the same situation here on an Intel 
DB75EN motherboard.

Regarding the keys, pretty much the same situation:

- same keys/content in the secure boot signature store (db)
- similar contents in the secure boot blacklist signature store (dbx) -- 
I have the same first entry, only the 2nd and 3rd are missing
- same keys/content in the Key Exchange Key Signature database (KEK)
- but I have no public Platform Key (PK) installed

The (literal) output on the screen is:

        Image Authorization Fail.
        System can not boot to this device due to Security Violation.

        Press Enter key to continue.

Thanks in advance,

Timo
