Hello There,
Also posted in Linux echo.
I just thought I would mention something that I noticed recently. I have a Intel based 64 bit P4 computer here that came with Windows 8.1. Some months ago I installed Ubuntu v16.10 64b on it. The install completed without any problems or issues. But I would randomly experience complete system lockups even with system sitting idle.
In testing I found that Ubuntu v15.10 seemed to run fine on the same PC. This time with v16.10 installed I decided to upgrade the kernel to v4.5.0. Since the
kernel upgrade the lockups are a lot less frequent.
This is a spare PC that I pretty much use for testing. I have three other PC's that all run Ubuntu v16.04 or v16.10 without any problems. They are all AMD 64
bit 8-10 core based PC's.
A second thing that seems to have helped is that using Ubuntu with a Intel based PC I edited the Grub config file and changed the line:
From: GRUB_CMDLINE_LINUX="quiet splash"
To: GRUB_CMDLINE_LINUX="quiet splash intel_idle.max_cstate=1"
Then updated GRUB and then rebooted.
So far the PC hasn't crashed or locked up once since the grub update.
