I found that dmesg returns this: ---------------------------[ cut ]---------------------------- ... [ 0.769467] [Firmware Bug]: ACPI MWAIT C-state 0x0 not supported by HW (0x0) [ 0.769532] [Firmware Bug]: ACPI MWAIT C-state 0x0 not supported by HW (0x0) [ 0.769586] [Firmware Bug]: ACPI MWAIT C-state 0x0 not supported by HW (0x0) [ 0.769681] [Firmware Bug]: ACPI MWAIT C-state 0x0 not supported by HW (0x0) ... ---------------------------[ cut ]----------------------------
So maybe https://askubuntu.com/questions/971477/ubuntu-17-10-keeps- locking-up-and-freezing-mouse-and-keyboard-input-doesnt-wor might be a solution. I will try that. I remember that Ubuntu 16.04 and Mint 18 (?) did not show this effect on the same machine. Also, Ubuntu 17.10 runs very stable on another machine here (laptop). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1777311 Title: System freezes randomly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1777311/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
