X-Enigmail-Version: 0.94.2.0 OpenPGP: id=4F9CF57E Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 2503 Lines: 73 I bought a VIA PC2500 board a few days ago - this new series of their mobos, This beast looks nice - after replacing their cooling system (that had a small fan on it) with larger but fanless, -- it becomes a almost real PC (1500MHz CPU), equipped with quite nice crypto and multimedia abilities, but with very low power consumption and very quiet. But the thing is - it doesn't quite work. It works generally - it boots, I can run my usual apps etc. But on a random (yet frequent) basis it segfaults here and there. For example: $ man man Reformatting man(1), please wait... $ man man Segmentation fault $ man man Segmentation fault $ man man Segmentation fault $ man man Segmentation fault $ man man Reformatting man(1), please wait... $ _ (this is 100% idle machine, just booted). (There are other - simple and comples - applications which inhibits this problem. For example, it 99% reliable segfaults on compiling aic79xx_core.c file in kernel, while all the rest (in my configuration anyway) compiles, at least after second attempt). It's definitely NOT memory issue - I tried several different memory modules (and different combinations) - the same results; I ran memtest86 for several days - no single error. I've seen a thread here on LKML about C7 and C3 CPUs back in March this year - tried with patch from Andi titled "i386: Enable CX8/PGE CPUID bits early on VIA C3" - it didn't change anything (this board does not lock up - not when booting nor when doing something, -- just random applications are crashing randomly, and the crash is always SIGSEGV; there's _nothing_ in dmesg about that, too). >From all the above it seems like something's broke on the motherboard (I've no idea what it can be however - because memory testing - which also tests for CPU cache for exampe - shows no errors; testing disk controller/disk using md5 does not show errors either, except of occasional SIGSEGVs).. However, being very curious about this, I tried installing 'doze on this machine - winXP. And that one went just fine without any error so far -- i tried stress-testing it as far as I can imagine, running various applications and workloads, -- no errors. So I'm kinda.. stuck about what to do next. Any.. idea, anyone? :) Thanks! /mjt - 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/
