Look like this is an issue of graphic driver (amdgpu). Please do a test: add nomodeset in the boot parameter from grub, then boot the system. Make sure the X11 is working in framebuffer mode. (lsmod | grep amdgpu; make sure the amdgpu is not loaded).
Then test if it still hang randomly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1801573 Title: pc randomly freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1801573/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
