Last night I was so close to get taking the motherboard out and returning it. Nothing I did seemed to fix my random reboot problems.

Being that returning something bought online is such a bother at times, I though I try one more thing. Just so I could say I tried everything if asked.

I move the ram modules around, from A B A B to A A B B, not how it should be. But that was how it was on my last motherboard, and I also under-clocked the ram.

The bios was showing it running at 1334, and I’m pretty sure this is 1333 MHz rated ram. So I pulled it down to 1066, I can take slower if it mean stable.

And when I got up after getting some sleep, it was still up with no reboots.

Thinking back in my googling I saw mentions of people having similar problems, that was fixed changing the memory. That didn’t really register with me till after I had under-clocked the memory. Maybe my subconscious mind was working on this problem better than I was. 🙂

Hopefully everything will just keep working now, and I wont have any more problems from this system (or at least for a very long time).

I’m back, and boy is it nice to read text on a screen larger than my hand!

Did run into a few problems, I got a Gigabyte GA-970A-DS3P motherboard and when booted to Ubuntu I quickly found that the usb devices and networking did not work. Some googling and I ended up enabled IOMMU in bios along with a xHCI and eHCI handoff options, and adding IOMMU=soft to the boot options.

That seems to get everything working, except for some reason networking, dmesg showed this: systemd-udevd[514]: renamed network interface eth0 to eth1 I remember this happening before and there is some file I need to update to prevent this renaming. But for the moment I switched eth0 to eth1 in the networking config.

Now to recover from swapping parts around and catch up with everything I put off dealing with on the tablet.

– edit –

I’ve been getting spontaneous reboots, no really pattern that I could see, happen on linux kernel 4.0 (self rolled) and 3.16 ( ubuntu), reverted bios IOMMU and the eHCI settings back to default to see if that helps.

If it doesn’t, I’m not sure what next to try to get this system stable.

Nope, went back and looked more in the CPU section of the bios, and turned off Core Performance Boost and C1E. I vaguely remember having to turn that off on other systems also.

I will have to wait and see if that will be the fix needed, certainly praying it is.

– edit –

I’m closing in on 3 hours uptime, I think disabling C1E was what was need. If nothing else pops up, this will be my last update on this post.

It’s now 2:39am, had another reboot, tried a few more bios options. Got back online and was looking at a different motherboard when I got a hard lock. That was the last chance I was going to give to the motherboard. I will remove it and return it for a refund, and get a different mb.

More updates on that in a future post.

My computer died last night, started off with a hard crash that forced a power reset. Booting back up I had a file system error and started to work out what was wrong and how to fix it, only to get kernel panics that looked to have more to do with the CPU.

It was while dealing with this that I came back to the computer to see a ‘insert system boot disk and press any key’ and this I started having problems booting, and the computer would crash at GRUB (boot manager). Then nothing, i pulled out a diagnostic tool I had that reports BIOS error codes, it stopped at FF the first code that bios gives out.

So it looks like either my motherboard or CPU gave up the ghost, if not both. And I don’t have any spare parts anymore to swap out to see which it might be.

Thankfully when talking about this someone offered to help me get the parts I need to revive my computer, but it might be next week before I have a working desktop. Till then at least I have this table to get online and do stuff.
