Description of problem:
System completely locks up during normal operation. Simple workloads e.g. a
Linux kernel compile repeatedly and reproducably cause a total system lockup
which requires a power-off/on cycle. The problem is not limited to kernel
compile scenario, running ImageMagick's "convert" program on a set of digital
photographs also crashed the machine. After a reboot the problem is
reproducable within 2 minutes running some non trivial workloads as listed
The hardware is an ASUS A7V8X board with a VIA KT 400 Chipset. The processor
is an Athlon XP 2000. Sound is disabled and no USB devices are attached. Disk
is a Maxtor 60GB in UDMA(100) mode. Two Ethernets are configured: (1) the on-
board Broadcom adapter plus (2) an Intel Etherpro 100.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.run kernel compile or ImageMagick's "convert" or run any other non-trivial
workload that stresses processor and I/O
Actual Results: system lockup, no panic screen
Using vanilla Linux-2.4.20, manually configured for the components that are
actually installed in the computer makes the system run without any problems.
I was wondering what the status of this bug is?
In the meantime I upgraded to RedHat 9 and the problem is still there. I have
tried vanilla kernel trees (up to 2.4.21-rc6) and the official redhat kernels
up to 2.4.20-13.9 and the problem is still reproducable.
PS: Is there any additional information that I could possibly provide?
I would recommend to run the memtest86 test (www.memtest86.com iirc) to test
your ram chips; and to check for bios upgrades...
have run memtest86, did not find any problems. Also have done BIOS update from
ASUS support site today (currently running Version 1012 Beta 9, file name
1012.011). The problem still persists.
Is this motherboard, or better the VIA KT400 chipset on it supposed to be
supported sufficently current 2.4.x linux kernels?
I am very close to giving up on this board, in case I go for a replacement,
would the A7N8x (with the nforce-2 chipset) be supported by RH 9?
KT400 works well with Linux. Except yours it seems 8)
I dont think its a simple incompatible hardware problem here
have replaced the A7V8X (KT400) mainboard with an A7N8X (nforce2) mainboard and
moved DRAMs and processor to the new board. Bad enough the problem persisted. I
would conclude that it is indeed not a problem of the KT400 chipset support in
the Linux kernel.
As a next step I have replaced the Athlon XP 2000+ with an Athlon XP 1400+
(ripped it out of another PC) and with that processor the A7N8X runs just fine.
I haven't verified yet whether this processor also runs fine with the A7V8X.
It seems like there is a problem with my Athlon XP 2000+ processor
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
