[Kernel-packages] [Bug 1788623] Re: regression: IPv6 PMTU discovery fails with source-specific routing
I started a kernel bisect between commit v4.14 final and v4.15-rc1. The kernel bisect will require testing of about 13 test kernels.

[Kernel-packages] [Bug 1788623] Re: regression: IPv6 PMTU discovery fails with source-specific routing
I'd like to perform a bisect to figure out what commit caused this regression. We need to identify the earliest kernel where the issue started happening as well as the last kernel that did not have this issue. Can you test the following kernels and report back? We are looking for the first kernel version that exhibits this bug: 4.6 Final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6/ 4.8 Final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8/ v4.13 Final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13/ v4.14-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14-rc1/ v4.14 Final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14/ v4.15 Final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15 You don't have to test every kernel, just up until the kernel that first has this bug.
