Hi, Grzegorz. Thank you for your response. On Sep 27, 2005, at 8:43 AM, Grzegorz Kulewski wrote: > What is your southbridge?

I spent the entire night trying to fix this, but of course, I gave up after some days of effort and decided to ask for help. > Anything in logs? Nothing in the logs. No oops, no stack trace, no nothing. :-( Oh, now that you mention it, I remember that I also made my Matrox G400 use speed 4x. I will try slowing it down to see if there is any influence on what I see. > Maybe sourthbridge or northbridge is simply overheating? Maybe you > have bad power suply?

I don't know, because lmsensors doesn't give accurate measurements, unfortunately. :-( > You can use http://pyropus.ca/software/memtester/ to check your > memory in linux.

I had already tried using memtester, but I guess that I was too ambitious with the amount of memory that I tried it to allocate. I will try this, but with my filesystem in read-only mode, as I cannot afford to loose what I have (and Debian's mondo/mind isn't working right now---I already filed a bug report that is shared by others). > I will bet that you have some hardware problem there.

I guess that I maybe wasn't paying too much attention. I will try it again.

Yes, I was just trying to avoid getting a new system now, with all the transitions going on (i386 -> x86_64 CPUs, PATA -> SATA etc). But my time is also costing me some nights of sleep... :-( It sucks not to be in the US, where things are cheaper. :-( Thank you very much, Rogério. -- Rogério Brito : rbrito@ime.usp.br : http://www.ime.usp.br/~rbrito Homepage of the algorithms package : http://algorithms.berlios.de Homepage on freshmeat: http://freshmeat.net/projects/algorithms/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
