Hi, Grzegorz. Thank you for your response.
Hi, no problem.

What is your southbridge?
The southbridge is a VIA VT82C686.
I know. I had the same southbridge in my Abit KG7 but I don't know if you
have version A or version B. I had version B and it has several disk
problems fixed. For version A there are some workarounds in the kernel.
Maybe there are some problems there with DMA or cables.
Humm, cables. I forgot to check that. I will check that as soon as I wake up.
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
I don't think that there will be any oops or something like that. But
maybe some IDE messages - like failed commands or something. But if there
are no such messages then chance is that this is some memory/mb problem.
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.
Yes, slowing down your graphics card could help.
Maybe sourthbridge or northbridge is simply overheating? Maybe you have bad
power suply? What are readings of temperatures and voltages in BIOS after
some heavy disk-memmory activities?
I don't know, because lmsensors doesn't give accurate measurements,
unfortunately. :-(
So after burning reboot fast end check the BIOS measurements. Temperatures
will not change that much in minute or two. If your system is overheating
they will be high for at least 5 minutes after reboot.
You can use http://pyropus.ca/software/memtester/ to check your memory in
linux. You can run cpuburn at the same time. And you can do some disk
activity at the same time (for example dd if=/dev/hda bs=200M | md5sum
several times to check if it will give the same results).
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. You can try to remove
the 256MB DDR module and turn HIGHMEM off. You can also try to check each
module separately.
I already checked each module separately, but I didn't see any corruption. I
guess that I maybe wasn't paying too much attention. I will try it again.
Thanks for the suggestion.
Hmm... What did you change before the system started not working? Maybe
try with only 256MB module installed if that was the working
configuration...
And the best choice will be probably to buy new mb (for example Abit KW7 or
KV7) because your is very old and it can start to silently break after so
many years... Today mbs are very short living parts - 3-4 years and they
are broken...
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
Yeah, I am waiting for stable and better x86_64 too. But I replaced my KG7
to KW7 in the mean time just to be sure I have something before I will
buy x86_64. :-)
also costing me some nights of sleep... :-( It sucks not to be in the US,
where things are cheaper. :-(
Yeah, it sucks. I live in Poland and we have really big prices for
computer parts here. :-(
Thank you very much, Rogério.
No problem.
