After upgrading my laptop (Dell Inspiron 5447) to Ubuntu 16.04 I saw that I can't shut down or restart after a few hours using the system. It hangs in Plymouth and stays that way until I force the shutdown by pressing the On/Off button.
As this is a common problem (there are tons of questions on the Internet) I tried to fix it, but none of my attempts were effective. Already tried:
- Boot with acpi=force, acpi=noirq and pci=noacpi;
- Disabling Swap;
- Run 'sync' before reboot or shutdown;
- Use another kernel version (4.7, 4.8, 4.9 and 4.10 from mainline);
- Disabling USB 3.0 in BIOS setting;
- Disabling TLP;
The most interesting thing is:
- I can shutdown/reboot normally using 14.04 and the kernel from Xenial HWE;
- The system is shutting down/rebooting normally if it doesn't have a considerable uptime (< 2 hours for example);
My Machine Specs:
Dell Inspiron 5447 - BIOS A10 Intel Core i5-4210 Processor 8 GB RAM 480 GB SSD Sandisk Hybrid Graphics (i915/amdgpu - Radeon R7 M265)
Does anyone know how to solve this problem?
