Additional Information:

Comment 1 Arjan van de Ven 2002-03-05 10:49:27 UTC

Is this an athlon machine ?

Comment 2 David 2002-03-05 16:11:56 UTC

Yes, this is an Athlon XP processor.

Comment 3 Arjan van de Ven 2002-03-05 16:15:03 UTC

This looks like the athlon bios bug from 55040 then... could you look at that
bug and see if the workaround ("noathlon") fixes your problem ?

Comment 4 David 2002-03-05 21:54:11 UTC

Do I just type linux noathlon at lilo prompt?  Also, I need to boot into 
console mode (runlevel 3), so should I just type linux 3 noathlon?

Comment 5 Arjan van de Ven 2002-03-05 22:00:53 UTC

Yes.
If that works I recommend upgrading to the 2.4.9-31 erratum kernel which has a
workaround for the bios bug included.

Comment 6 David 2002-03-06 21:25:12 UTC

Thanks a lot... the noathlon option seemed to work perfectly.  I am going to 
upgrade to kernel 2.4.18.  Do I still need the noathlon option, and if so what 
should I put in the lilo.conf file to make it permanent?

Comment 7 Arjan van de Ven 2002-03-06 21:27:14 UTC

2.4.18 should have the same workaround;
if not add
append = "noathlon"
in lilo.conf

Comment 8 David 2002-03-13 13:52:06 UTC

Thanks, everything seems to be working now.  What exactly is the athlon bug?

Comment 9 Arjan van de Ven 2002-03-13 14:09:24 UTC

Some bioses leave the chipset in debug mode, and the chipset then "crashes" if
there's too much load on the memory bus. "noathlon" disables the kernel's fast
memcpy() implementation and therefore reducing the load the kernel puts on the
memory bus.
