[Kernel-packages] [Bug 1788782] Re: Ubuntu 16.04.03(P8/Tuleta): SEGV-panic in smp_send_reschedule(). Machine keeps rebooting with oops message even after reboot.
I built a test kernel with commits 1bd6a1c, ced1bf5 and a581831. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1788782 Can you test this kernel and see if it resolves this bug? Note about installing test kernels: • If the test kernel is prior to 4.15(Bionic) you need to install the linux-image and linux-image-extra .deb packages. • If the test kernel is 4.15(Bionic) or newer, you need to install the linux-modules, linux-modules-extra and linux-image-unsigned .deb packages.
