(In reply to Bráulio Bhavamitra from comment #464) > You freeze seems GPU related, try a new kernel/firmware
I also have got amdgpu crash with same screen freeze, but magic key had worked that time and error left in kernel log. And I was able reproduce that with certain game in dolphin emulator. My random freezes happened without any special program running, sometimes in clear gnome-shell desktop. But this never happens just after power on - only after some working time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1690085 Title: Ryzen 1800X freeze - rcu_sched detected stalls on CPUs/tasks To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1690085/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
