In the next KnoppMyth release, if you install/upgrade a Dragon 1.x system (or one that uses its motherboard) and use the boot parameter dragon it will put the necessary kernel boot parameters in place to fix the time drift.

Something strange is going on...

The time change was fine, and then it resorted back to it's old pattern of losing 12 seconds every 5 minutes:



The first time I tried this, I set my append line to:
That worked for a few days until the box was power cycled, but after that it went back to losing time.

My current append line is:


What are the dragon boot parameters?

The Dragon is no different from your parameters. The Dragon 2 uses:

Mephi, the parameter you're missing is "acpi=off"

Thanks, I'll give that a try.

Ok I appear the have a similar issue on my MBE.
It uses the Dragon 1.1 mobo as the base setting.

I didn't choose Dragon in the boot options when I did the upgrade to R5F27 and set it up because I had a challenge working through backing out some of the other settings when I initially built it as an R5C7 box.

It has been built for about 1 week or so now and I noticed twice now that the system time suddenly drifts like 5 plus minutes from the Hardware clock. So I am thinking I need to apply this edit to Lilo.

So I am clear
My original lilo.conf is this:


I need to change my lilo.conf to something like this.


Then I need to run lilo as root and reboot.

TIA

The acpi=off is the only option I think you need, but the others shouldn't hurt you. You can always refine it as you go. And yes, just re-run lilo as root when you want to implement the changes.

I will try adding just acpi=off again to my mbe tonight.
I tired it last night and it took a long time to boot, then I noticed the backend did not start and it couldn't find the LVM.

I went back to the original lilo.conf and ran Lilo and it started fine.

Once i do this are there any other changes I should do as well?

I do recommend using libmpeg2 as your MPEG2 decoder, since it seems to work best with that motherboard and Athlon 64 CPUs. Other than that, there aren't really any other performance-related enhancements that I can think of.

When I insert acpi=off into my Lilo.conf and run Lilo I see this at boot.

mp-bios Bug: 8254 Timer not connected to IO-APIC

When it gives me that I also cannot get the Backend to start and I see that LVM is not loading.

I just reset my Bios to Optimized defaults no change.

So since I have this down to a pretty straightforward process I went back to the Drunken Monkey instructions and am trying a Rebuild with the Dragon v1 scripts.

I am at the moment still seeing this error above when it restarts and it takes a long time to get there.

Were there any Bios Tweaks I need to make to rectify this message above?

Other than the time drift issue, which wasn't present in R5C7 The R5F27 has been rocksolid, way better than the previous build. IMO at least.

TIA

All the BIOS tweaks that we used to do for Dragon 1.x are listed here: http://mythic.tv/DragonInstallationGuide.html

Other than that, I don't know why you'd get different behavior with the same motherboard.

Human,
It has me puzzled as well. I really appreciate you taking time to respond on this, especially since you have a business around these.

That is commendable.

Anyway, I doubled checked my settings against yours and they were still the same as I had used before.
I appear to have a couple of configuration quirks in my setup from yours, because when I built it as Dragon v1 it wouldn't rebuild my database etc.

Now I reset the Bios settings and I am rebuilding back to what I had before.
Once I get back to my functioning system, I am going down that path to turn off ACPI. I have been googling a bit on this issue, foudn a lot of discussions and no specific answers. I did however find one suggestion to turn off APIC as well.

I haven't done that yet. I'll post back the results of that effort.

Well I finally got the acpi=off to work

Here is my lilo.conf


I put this in replacing the original and then ran lilo as root.

The system boots now and the Knoppmyth platform works.

However, I have lost LIRC control and I noticed in bootup there are several modules not loading, so I am thinking I have other problems with that configuration.

So I am going backwards to my original configuration.

See if I can find another issue that fixes the time drift issue.

Thanks for the help.
