Forgot to comment there (only did it in private on IRC). The binary above doesn't print anything to screen in my case, it's as if grub was somehow preventing the shim to render anything on screen.
My suggestion is to use a nvram variable accessible from the booted system and use that to store the debug output. However be careful to only log a very minimal amount of data as my mention suffers from the UEFI garbage collection bug that bricks machines when more than 50% of the nvram variable space is used. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1087501 Title: Unable to boot unsigned kernel, boot freezes in shim call To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1087501/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
