This is (mostly) harmless.

This is likely to mean a hardware problem (memory, cabling, thermal problems) --
something is corrupting the data. Please exclude possible kernel problems by
compiling and installing the most stable kernel so far --
2.2.7. Please use the official 2.2.7 kernel. Be smart when confuguring it (do
not enable APM for example). Use gcc (not egcs!!!) compiler when building. Once
you have installed custom configured 2.2.7 kernel, run crash tests on the system
and see if it passes it.
Hre is a possible crashtest (must be run in /usr/src/linux):
#!/bin/sh
ARGS=""
if [ $# -ne 0 ]; then
ARGS="-j $1"
fi
for i in 0 1 2 3 4 5 6 7 8 9
do
for j in 0 1 2 3 4 5 6 7 8 9
do
make dep; make clean
echo compiling $i.$j series...
make $ARGS zImage > log.$i.$j 2>&1
done
done
For an amount of memory >= 256MB run it with argument "8". If you have less than
128MB of RAM, run it with argument "4". (Specifying an argument larger than 2 is
crucial for the test to be meaningful.) The test should generate 100 log files
in /usr/src/linux, all of them of the same size (except maybe log.0.0) and the
machine should not freeze during the test.
I hope that helps.
