Computaion Error - ERROR: Stepped outside the coarse grid!

I'm killing E@H WUs and need help figuring out why. I need help. I don't know everything that you may need but this should get us started.
Running SUSE 11.3. (Linux 2.6.34.7-0.5)
Tyan K8WE Bios 1.06
Dual Opteron 275 (4 cores)
8Gb Ram
Boinc is running from a directory from which I have permissions.
I *think* I have the 32-bit libraries installed.
I've run the memory test with the Linux 'boot' disk.
I've swapped out motherboards.
Leave tasks in memory while suspended -Yes
I do not recall having a problem when I ran XP on this machine, but I never looked. I do know that I suspected something because this system should have run faster than another I was running but never did.
Very few WUs go to successful completion.
Most end with computation error. This can happen from right away to the very end of the WU.
When I look at the WU I see "ERROR: stepped outside of the coarse grid!"

We're getting some of these errors recently. My current guess is that it's another symptom of the "preemption kernels", see e.g. this thread. Try a different kernel.

RE: We're getting some of

I tried to read through these, but was not able to make the changes needed. How do I run a different kernel? Do I need to just run openSUSE 11.1? Can someone please tell me if I can change some configurations or what I need to do to be able to crunch E@H.
Thanks for your help.
RE: RE: We're getting

Reboot your machine, and when you see the message to do so, hit a key to bring up the boot menu. If you see a "default" kernel, choose to boot from it. (Ironically, the "Desktop" kernel, which is likely the source of your problems, is actually set as the default.)
If the "default" kernel isn't installed, open YaST and install it from there.
RE: RE: RE: We're
)
Yes. I get to choose between the default (desktop) and failsafe. The desktop option is the one that has been not working.
Should I be using the failsafe?
RE: RE: RE: RE: We're
)
No, unfortunately, this is a bit confusing. (But then, most things with OpenSuSE are, which is one reason why I hate it.)
The "Desktop" kernel that's set as the default, isn't the same as the kernel that's named "Default". To help clarify, here are the relevant lines from my GRUB configuration file.

Here, I have both the "Desktop" and the "Default" kernels installed. And, it happens that I have the "Default" kernel set as the default for when I boot the machine. But, I could easily change that to make the "Desktop" kernel the default. (Yeah, it sounds crazy, but that's the way the SuSE folk do pretty much everything.)
Anyway, it sounds like you don't have the "Default" kernel installed, so you'll want to open your package manager and search for a kernel with "default" in its name.
I found the default kernel in
)
I found the default kernel in YAST and installed it. I now have it running and downloaded some more WUs. We'll see in the morning how this works out.
I sure hope this fixes it. Then I'll only have to automate it and forget about it.
I'll post back on how it goes.
RE: I found the default
)
That should fix it. The "Default" kernel has never caused a problem on either of my OpenSuSE boxen. (By the way, whatever happened to the guy who always used the word "boxen" in his posts?)
