I'm seeing similar behavior after updating to 4.15.0-151, with multiple crashes and hangs. My CPU is a i7-6600U.
The message in the dmesg log from the last crash is 'BUG: unable to handle kernel paging request at 0000006a18e6bfe5' I've attached the full trace in case that helps. I also seemingly have some older (but after updating to 4.15.0-151) crash logs in /var/crash/ that I can also share if these are helpful. ** Attachment added: "151_kernel_crash.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1938013/+attachment/5514352/+files/151_kernel_crash.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938013 Title: 4.15.0-151 is freezing various CPUs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1938013/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
