Once in about every 2 days, it seems to lock up randomly.

Try setting the following boot options:

noapic nolapic pci=noacpi

Regards,

I have a server with Hardy server edition installed (2.6.24). No GUI
on it. It runs apache, mysql, is an NFS client and Samba server. Runs
some of our custom scripts, nothing major.

Once in about every 2 days, it seems to lock up randomly.

Fortunately, it has an IPMI card and I programmed it to run an IPMI
watchdog, so it reboots itself very quickly upon lockup,
automatically. Still, I obviously do not like it in the least and hope
for something better.

If there is something that I can do, like enable debug mode of some
sort, etc, I will be happy to get started.

Probably hardware/heat.

Look at logs.

I do not think so. The server is not that busy.

after disabling ACPI, I will explore this possibility using sensors.

where in menu.lst should I specify them? Any idea?

That has nothing to do with flakey hardware. Or a clogged fan. Its summer
in the northern hemisphere..all sorts of margnal electronics kicks over the
traces ..I could bore you with a weekend of equipment failures due to heat,
but i wont.

The server is almost new,

More reason to suspect hardware, I'd say. What is the longest uptime
you've had?

Anyhow, there are better ways to debug hardware issues. A memtest
would be in order. Smartmontools to check your disks for bad
sectors. Review your hardware for ISR conflicts (such as can be
attained by insterting two identical PCI serial port adapters into
one machine). But you probably knew that.

This is a brand new supermicro machine, they would not put such things
in there. Anyway. I am trying 2.4.25 kernel right now, and so far,
it's been almost 9 days and counting and it is still up.

I have a machine with a SuperMicro motherboard that I put together myself.

I have a machine with a SuperMicro motherboard that I put together myself.
It ran Red Hat Enterprise Linux 3 just fine for about three years or so.
Then I upgraded to RHEL 5 and it works just fine too. X5DP8-G2 motherboard.
All the Supermicro motherboards I looked at at the time I was building this
were claimed to run with Linux. I am running the kernel from this rpm:

kernel-PAE-2.6.18-92.1.10.el5

that is the latest one for RHEL5.

The only trouble I have had is that I could not run an ISA sound board with
a 2.6 kernel, so on my old machine I had to put in a similar PCI one. But
that did not stop anything from booting; I just could not hear anything with
the sound board.

By the way, I have seen a lot of Linux lockups.

Let's see, Fedora 4 locking up, Fedora 3 doing same, this Ubuntu Hardy
machine, Ubuntu Gutsy machines, etc etc.

I admin 2-3 dozen linux machines and yes, I have seen plenty of
lockups.
