Grub cannot read Event Log #20

Hi,

I checked the device with napper (and it said the device is vulnerable). I installed an Ubuntu 18.04 on an USB stick and build the bitleaker tool. When i start the stick, it says that the uefi event log cannot be read due to invalid parameters. On another machine, grub can read the event log, but the device is not vulnerable. The differences of the two devices is, that the vulnerable device uses an Intel fTPM and the other a dTPM. Has anyone a clue, where the error is? I changed nothing.

Fixed it for myself.

Can you share how you fixed the boot loader invalid parameters ?
