I'm running RH7.3 with an AMD K62000 on an albatron 400+, kernel 2.4.20,
with a Radeon AGP card (7500?)  that has random kernel panics. Sometimes
it will stay up for days, other times its down in a matter of minutes.
Are there any known issues with this hardware configuration?

Otherwise, I've found the netdump utility to send the kernel core over
the network, is there a way I can just save it to disk and either
forward it to Redhat or piece through it myself to try and find out what
exactly is causing the panic? Or is it already saving somewhere and I
just don't know where to find it?

I've been using redhat for years and have never seen anything this
unstable - maybe because I wasn't building the system ;).

TIA,
Chris

Are they "panics", lockups, or what? If any tracebacks happen,
are they different each time? Anyhow, you aren't giving any info.

I had something similar on a somewhat older system, but it might be the same
problem. There seems to be a problem with some AMD K6 processors. IIRC they
mess up memory addressing when they get too hot. I first noticed my problem
when I was running seti. From the moment I started it, I had at top 2 hours
before at least seti crashed. But in some cases my whole system would crash.
I had the problem before when trying to build kernels, but due to my
inexperience at that time I thought I just did something wrong with the
kernel building.

In any case, eventually it turned out that the cooling of my power supply
was broken, and the cooler of my processor was insufficient. I replaced
both, and the problem has never occurred again.

So my advice is to check if you have applications disappearing or
segfaulting spontaneous, and see if this AMD K6 bug applies to your CPU, and
if you have enough cooling for your CPU.
