I just finished building my new PC. After I installed ubuntu and the latest nvidia drivers Spring crashes straight away. It starts, but after I select a script it crashes.
Terminal Output
rutter@stumpy:~$ spring

rutter@stumpy:~$
8600 GTS with nvidia drivers installed via envy.

Your computer is named stumpy, and that is awesome.
Did you try the 'commanders' script? the air combat test uses the xta unit names iirc.

How do you know when you've been playing too much spring.
You name your computer after a unit in BA/AA/CA
How do you know when you've been playing FAR too much spring.
When you associate everyday words with units from BA/AA/CA.

It's supposed to. After it freezes, type
in the gdb line and post what comes out of it.

O please don't say it's the RAM.

it's hard to tell, TBH. unfortunately, this backtrace is not helpful, and the fact that it's repeatable is suggesting a software failure rather than hardware. If the memory address remains the same accross runs, you can be 100% sure that it's a bug somewhere, but I can't even vaguely tell where. (Well, maybe I can: afaik spring runs threads only for networking - therefore the crash may be happening somewhere in the netcode.)

Well I ran it again after rebooting. The same problem, slightly different output:

Alright, I'm not sure if you can do this, but get a boot CD of memtest33. Test your RAM using it, should take several hours - I ran it for 36 just to make sure. If it crashes, you either have heat issues or bad RAM sectors. Anyway, that will either give you the cause or rule out the worst case scenarios.

Yeah, I have memtest. I'm planning on doing it a little later today.

No worries RAM has full time warranty!!!

Yeah, if anything is wrong I will just RMA it. Memtest is running right now. So far no errors and cooling is fine. My system temp is in the low 30s C.

Well I let it do 6 passes, which took just under five hours and no errors came up. I'm going to be reinstalling ubuntu a little later, so for now I guess this is going to be on hold. Spring works fine under windows, which is good enough for now.

Everything is now resolved. I did a two things, not sure either any of them were the cause. I found that the stock voltage for the RAM on my mobo was 1.8v, but my RAM had a recommended voltage of 2.1v, so I set the BIOS to +0.3v. I also reinstalled ubuntu in case something was wrong with the installation.
Everything works as it did before, thanks for helping me.
