Hyperstransport Sync Flood Error

[taughttoxique]

Hi everyone,

First of all, I have to tell you I'm really new to linux-Ubuntu.

About a weak ago, I build a small computer rig to have my GPUs do some calculations. Everything worked fine until about 3 days ago.

I started having some problem with my wireless pci card. It seemed like there were some sweet spots for it to work (it it was moving just a bit I would lose the internet connection).

Then, yesterday, I started having another bigger problem. I was not able to boot at all. Sometime I would be in front of a blank screen and some other times I would receive this message : A Hyper-Transport sync flood error occurred at last boot.

I'm writing here about this last problem, since I don't understand if it occurs because of my mobo or my cpu (I googled that, but it seems people are talking about those two).

Some people seem to have find some solutions by calling some commands in the terminal, but I can't even access to my login screen.

I also tried to do a fresh installation of ubuntu 11.04, but every time I'm lauching from my dvd-writer, it would bring me to the ubuntu loading screen (with the 5 little dots) and freeze there.

So, does anyone have ever had this problem before and found a solution?

-Edit : I know this problem is probably not in relation with ubuntu, but I'm still asking in case someone here would know the solution

Note : I'm using the exact same setup on another rig and everything is working no.1

I'm thinking about something ; if there is those said "sweet spots" for my wireless pci card to work, do you think that this may be the problem? When I'll be back home I'll try to remove it and see if it does any differences but meanwhile would you think this could be the problem (since I'm reading this error occurs because of voltage)

I have an MSI ddr2 MB with AMD 965 Quad Core CPU running 11.04 and Mythtv. I started getting that error after I put in a new stick of RAM.

Turns out it was not the ram. It was heat buildup. I got a couple of Scythe Ultra Kaze 3000 RPM 120mm case fans and installed them and no more sync flood errors.

Granted it is as loud as my 16 drive rackmount RAID file server now. But its a small price to pay. Case is cool, temps are down all is well for 7 days so far.

Easy thing to cehck is to pull the side cover off the case and let the heat out, see if that helps. Once I did that I know the MB was getting too hot. Then I got the fast case fans.

$10.88 shipped each on eBay for the fans.
