Problems has just occurred again (I'm making verification): the system hangs just after almost one hour in idle state without any application used when I just open the start menu moving the mouse towards the icon from which run the browser.
Obviously I returned the grub file to its original state deleting the workaround. The problem has happened after much more time in confronto of the previous kernel however it has happened. That's some kind of issue on ACPI events to manage C-states (so that the hardware is faulty and/or bios is broken and/or kernel is defective). Other info: bios: 1) bios ehci hand-off: disabled (enable or disable appears to be irrelevant); 2) cpu q-fan control: enabled on optimal (this option seems to increase the problem). I'll wait for another hangs then I'll apply again the aforementioned workaround if it fixes the problem affects the kernel or the hardware. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1704374 Title: system randomly hangs itself Status in linux package in Ubuntu: Incomplete Bug description: this problem affect my system on Kubuntu 17.04 64bit Kde Plasma: 5.10.3 kernel: 4.10.0.26 Kde frameworks: 5.36.0 Qt release: 5.7.1 Probably I've solved with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=1" Randomly the operating system hangs both eist and or c1e options enabled or disabled.
