I was able to determine those upstream versions by looking at the Saucy changelog. The Ubuntu 3.8.0-27 kernel was based off of upstream 3.8.13.4 and we know that did not have the bug. The Ubuntu 3.8.0-28 kernel was based off of upstream 3.8.13.5, so it was just a matter of testing and confirming.
The next step is to perform a kernel bisect to identify the exact commit that introduced this regression. It will require testing about 6 kernels, which I will build and post links to here. After I build a kernel, I'll post a link to it here for you to download and test. After your testing, I'll build the next kernel based on your results if the test kernel had the bug or not. Eventually it will narrow down to one commit. I'll post a link shortly with the first test kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1237392 Title: kernels following version 3.8.0-27 do not start To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1237392/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
