Stéphane has reported that with the build of shim 0.4, the problem is worse: both signed and unsigned kernels now fail. This seems to fit if the bug is in shim's own image verification - between the raring version of shim and shim 0.4, upstream has changed to use its internal SB verification code exclusively, instead of trying the firmware's verification routine first and falling back to its implementation only on failure.
Stéphane, can you please give the attached shimx64.efi a go, and post the console output so we can see where it hangs? Binary signed with the same key as the other one for bug #1187233. Will need to iterate this a few times to get to the bottom, I expect. ** Attachment added: "shimx64.efi" https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1087501/+attachment/3731196/+files/shimx64.efi -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
