Would it be possible for you to do a kernel bisection? First, find the last good -rc kernel and the first bad -rc kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/
Then, $ sudo apt build-dep linux $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git $ cd linux $ git bisect start $ git bisect good $(the good version you found) $ git bisect bad $(the bad version found) $ make localmodconfig $ make -j`nproc` deb-pkg Install the newly built kernel, then reboot with it. If the issue still happens, $ git bisect bad Otherwise, $ git bisect good Repeat to "make -j`nproc` deb-pkg" until you find the commit that causes the regression. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1783358 Title: Xenial linux 4.15.0-29-generic kernel panic. Status in linux package in Ubuntu: Confirmed Bug description: After update to the 4.15.x kernel my system cannot boot. It freezes after grub menu. I tried to boot recovery mode and saw kernel panic. Now my system can boot only on 4.13.x kernel. I tried 4.15.0-25, 4.15.0-24, 4.15.0-23, 4.15.0-22, 4.15.0-20 and had the same results. I saw similar bugs in the bug tracker. So I waiting for updates.
