Stable System?

I think I can finally say I have a stable system once again. After the RMA replacement of my Ryzen CPU to fix the “Performance Marginality Problem” I noticed that I was still getting some regular system lockups/freezes when it was left idle.

How long this secondary issue has been present I am unsure. Over the summer I had been using the machine but turning it off after use as it was keeping the room a little too warm. I probably didn’t notice the idle issue as I wasn’t leaving it idle. Any occasional occurrences of problems I attributed to the old CPU.

The current workaround has been to disable the C-States in the BIOS. It appears when the system is idle it is going into a low power mode but for some reason this isn’t happening correctly. At this time I’m unsure if this is related to the BIOS itself or Fedora 26 running a 4.13 kernel.

I have upgraded both BIOS (AGESA 1.0.0.6b) and kernel over the past few months so I will have to test again when one of them changes. Next week Fedora 27 is released, it will likely ship with a 4.13 kernel but 4.14 should follow shortly after. A BIOS with AGESA 1.0.0.7 might arrive before the end of the year.

For the time being I will settle for a little additional power usage and no crashing.

Kernel Upgrade Day

It has been a long time since I last updated the kernels on my linux machines. I had managed to keep the software up to date but the kernel upgrades are always a little more involved. Today is the day that they were all updated, all the software updated and rebuilt. Optimising the kernels is a little more time consuming and it may take another attempt on my main machines to get rid of any extra drivers and features that are not required.

I wont be suprised to see another kernel released any moment to undo my hard work, its just the way it goes.

Gentoo Linux – Toshiba Satellite X200/X205 (part 6)

I have been happily using my notebook without problems since I posted my last update. I was enjoying using it so much I decided to take advantage of the low RAM prices and upgrade from 2GB to 4GB. Running a 64bit version of Gentoo I was just expecting to plug the stuff in, it be detected and that be the end of it. To my horror the bios reported 4GB but Gentoo was only seeing 3GB. The majority of posts of people struggling with 4GB of RAM were those running a 32bit system. I applied 2 bios updates to my system (currently running bios version 2.10) in the hope that would fixed the problem, alas no.
