Just to factor out any specific BIOS/CPU issues, can you try with the kernel option: processor.max_cstate=1
Edit /etc/default/grub and change: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash processor.max_cstate=1" then run: sudo update-grub and reboot. I just want to ensure that the hangs aren't caused by the CPUs going to a C state that causes this hang. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1697132 Title: CPU Cores Stalls/Lock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1697132/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
