I just put together a new computer system, installed linux, and
am suffering a series of random system freezes.
AMD k6-233, clocked at 3.5*66
Shuttle HOT-603 motherboard
Mitsumi 24X CD-Rom drive (slave drive on 1st ide channel)
Fujitsu 3.2 gig HD (master drive on 1st ide channel)
64 meg SDRAM (1 DIMM, w/ EEPROM; gold contacts)
Jaton 58P 4 meg video card (ET6000 chipset)
mid-tower case, 230W ps
I have a 500 meg ms-dos (6.2) partition,
the rest is devoted to linux. (all logical partitions (hda5 is root,
hda6 is swap, hda7 is /usr, & hda8 is /home)
I picked up the infomagic 6 CD-ROM "Developer'" distribution, then
first installed redhat 5.0. (kernal 2.0.32) I had several crashes,
reinstalled a couple of times, then decided to put slackware 3.4
(kernal 2.0.30) on, since it's what I had on my old 486, and I
never had trouble with it.
Well, to make a long story short, the system crashes under slack-
ware too. I have no clue why. Sometimes it crashes while boot-
ing, sometimes it doesn't crash at all, despite being used for
a couple of hours. Once it crashed right after logging in.
To date, I've only had one crash under ms-dos, and that was while
using a program I would expect to crash occasionally. True, nothing
I'm using in dos is going to stress the system very hard, nor use
anywhere close to all the memory.
I suspected that the ram might be the source of the trouble, so I went
looking for memory test programs. Unfortunately the few I can find to
download either are too old to recognize all the ram I have, or seem
to lock up. At first I interpreted the lockup as a sign of memory
trouble, but further investigation makes me suspicious of the program's
accuracy. Specificly, when I directed the program to test ram higher
than ~16 megs, it reports an error every 4 megs or so. Under 8 megs
it says everything is ok. Between 8 and 16 megs it locks up the sys-
tem. If I were to believe the ram test program, I have some *really*
crappy ram. I have to admit that I find it hard to believe that so
much of my ram is screwed up.
If anyone could direct me to a *useful* ram test program, I'd hopefully
be able to determine whether it is the source of the problem.
Other than the ram, the best guess (hardware-wise) I have is that
my power supply is extremely erratic. Unfortunately I don't currently
have the equipment to test it.
Originally I thought that perhaps it was something due to my linux
setup, but I've checked over it and it all seems ok.
I went step-by-step through my motherboard's reference card and made
sure I had all the jumpers set correctly, and set all the memory
timings to very conservative values. (more so than the standard/
Currently I'm stumped, and hoping to figure this out soon, so I can
return defective parts to the resaler, if necessary.
If anyone can shed some light on my problem I would greatly appreciate
it. Shoot, if you can direct me to the appropriate document (I've
been looking through how-to's & faq's) I'd be happy.
If you do respond, please cc the message to my email address as well
as posting to the group, as my news server is somewhat erratic.
