** Description changed: + ### HOW TO BOOT INTO PREVIOUS KERNEL IF UNABLE TO BOOT ### + + If you hit this bug and are unable to boot, you can boot back into the + last working kernel. To do that, select that version(Probably + 4.4.0-104) from the GRUB menu. + + The GRUB menu can be accessed by holding the 'Shift' key after powering on the system(Some systems require the 'ESC' key to be held instead of Shift). Detailed information about GRUB can be found here: + https://help.ubuntu.com/community/Grub2 + + + [Description] When using PPA https://launchpad.net/~canonical-kernel- team/+archive/ubuntu/pti/ to fetch the candidate kernels for CVE-2017-5754, CVE-2017-5715 and CVE-2017-5753. There is the same kernel trace shown in many different pre-installed Ubuntu images of different platform. So far these platform are known to reproduce this issue: CID 201606-22340 (Dell Vostro 5468) CID 201606-22349 (Dell Inspiron 7560) CID 201606-22365 (Dell Inspiron 5767) [Steps to Reproduce] 1. Install the target pre-installed image (Xenial 4.4-based stack) for the platform. 2. Fetch the kernel 4.4.0-108.131 from this PPA https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/pti/ 3. Update the system by "sudo apt-get dist-upgrade" 4. After the system update, reboot it. 5. Check the syslog after the system is ready to use again. [Expected Result] No kernel trace message.
