So, it looks like bug 1830433 didn't fix this problem... assuming it's still an x86/mm issue, it'd be interesting to test another kernel (I've applied a few more x86/mm-related fixes).
This new test kernel is available at the same place: https://kernel.ubuntu.com/~arighi/LP-1827884/ As correctly pointed out by Tyler, for the test you should remove "mitigations=off" and "nopti" and in case of success, please report the output of: $ cat /proc/cmdline $ cat /sys/devices/system/cpu/vulnerabilities/meltdown Thanks again for all the tests! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1827884 Title: Boot problems after upgrade to kernel 4.15.0-48 (18.04.2LTS/i386) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1827884/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
