Hi all.

I have a box that I really want to run the seti on but it keeps crashing. I've had the box for over a year and I built it myself (no trashing me for that one, I'm not horrible at that part). The board is an MSI K9N Neo-F V3. It has 1 GB of RAM and an AMD Athlon 64 X2 (dual core) 4200+. Its been running stable versions of Ubuntu since I built it, currently 9.04. It is stable using it as a desktop. However, within a few minutes after starting up my boinc client it kernel panics (X is frozen and keyboard lights are blinking.) I've kill off the desktop so I just boot to the console and have turned on crashdumps and some other debugging stuff but I've yet to get a core or crash dump. Since you all are *nix geeks as well, perhaps some of your knowledge and experience can point me in the right direction. I've ran various kernels/versions of ubuntu and different binaries for boinc and seti on this machine ... all with the same result so far once boinc starts up and attaches to the project. Let me show you what I have on it and perhaps some of you can direct or asisst me. In this dump, only one of the seti processes has crashed and the system is still running so I have this:

I recommend to check your hardware (CPU, Memory, Cache, ...). SETI does intensive CPU, cache and memory operations, so a crash could point to a hardware problem.

Are you sure you have the right version for your OS and CPU? Better check it (again) to make sure.
