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!
