Hello,
I installed Linux again a couple of months ago, had been running Windows
for a while. Ever since that I have had a problem with random system
crashes. These crashes occur very randomly in time, the computer may
have been running for between 5 miuntes and 10 days. However, they most
often occur after the system has been running for 1-3 days. They appear
almost exclusively when I'm at the computer doing something; almost
never when the computer is idle. Often before the whole system locks up
various programs segmentation fault. Associated with these program
crashes klogd report kernel oopses. Check the bottom for a sample of
them. It seems to me the crashes occur more often during heavy disk
reads, but I am not really sure about that. Sometimes the scroll lock
and caps lock leds flash simultaneously when the system is in the
crashed state, but sometimes not. Until the system freezes everything
works perfect.
My system froze under Windows too, but it is hard to tell if it was the
same problem since I was using an application that was quite unstable
and many friends reported crashes when running it too.
Before switching to Linux I added one memory module and an additional
hard drive. However, I've been trying to run the system with either
one of the memory modules (in different slots too) but without any
difference. I have not tried running the system without the new hard
drive since I really need it.
I have tried running memtest86 on all combinations of memory (both
modules and either one of them), but memtest86 seems to freeze. I get to
a blue screen with a red bar at the top with the version number. A
cursor is blinking but nothing more happens. I left it in that state
over a night but no change occured.
I have searched the web and usenet for hours without finding much
useful.
I am extremely grateful for any help.
Kind regards,
Kristoffer Erlandsson
-----------------------------------------------------------------------
My system specs:
Debian unstable
Kernel 2.4.20
gcc 2.95.4 (other versions too, but the kernel was compiled with 2.95.4)
libc 2.3.1
Hardware:
AMD XP 1800+ at 1533 MHZ
2x 512MB DDR-DIMM PC2100 CL2.5 (only one inserted now due to testing)
Abit KR7A Motherboard using VIA VT8366A and VT8233 chipsets
Creative PCI SB 128 Vibra
Cnet Pro 10/100Mbit NIC using Davicom DM9102A chipset
Western Digital IDE ATA-100 60GB 7200RPM 2MB cache (WD600BB) (Running
one ntfs partition and one ext2 with the operating system in question
on)
Western Digital IDE ATA-100 120GB 7200RPM 8MB cache (WD1200JB) (Running
two fat32 partitions)
LG CD-ROM CRD-8522B 52X
Creative 3DBlaster GeForce4 MX440 64MB AGP (Running Nvidia's driver)
A sample of two oopses:
(Maybe worth noteing is that all oopses I have looked at end with
an instruction accessing %e*x, where * is a letter a-d. I do not know
what this means, but I thought it was worth mentioning for those more
skilled than me. I can produce more oopses on request, I do not want to
make this letter any longer.)
