A little background: For the first several releases of 2.4, I couldn't
get one to work on my T-bird (symptoms in a moment). Turns out that
when I disabled "Local APIC support on uniprocessors", it worked fine.
This surprised me greatly since the help for this says, "If you say Y
here even though your machine doesn't have a local APIC, then the kernel
will still run with no slowdown at all."
As for the symptoms I experienced, random processes were causing kernel
panics/oopses with great frequency, and the system was unusable because
of this; also, the system would fairly quickly hang on one of the
oopses, and I do mean lock up hard.
I experienced this also while installing some version of RedHat (7.2, I
think). I don't *quite* remember, but I think that adding the
aforementioned 'noathlon' to the kernel command line ("append=" in lilo,
or the "kernel" line in grub) took care of the problem.
