Mysterious server lockups with Ubuntu Hardy

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.

One of the following should help in case there's some kernel log text which
isn't making it to disk:

http://www.mjmwired.net/kernel/Docum...al-console.txt
http://www.mjmwired.net/kernel/Docum...netconsole.txt

It may also help to add "debug" to the kernel command line.

Thanks. I doubt that I will see anything, however, it is good not to
presume too much. I will definitely try it. Thank you again.

I was able to insmod netconsole.

root@server:~# modprobe netconsole netconsole="1941@10.1.xxx.xxx/eth0,1941@192.168.xxx.xxx/00:14:xx:xx:xx:xx"

mypc:myusername:~ ==>nc -u -l 1941

However, I did not receive any kernel messages on the target machine.

That's despite having generated some kernel messages by inserting a
superfluous module and verifying that with dmesg.

Try setting the following boot options:

noapic nolapic pci=noacpi

The IP addresses say that you're using two separate logical networks. That's
fine, so long as the destination IP address is routable and the destination
MAC address is one hop away from the source machine (the server). Is this the
case?

That could be it.

I have modified the line in /boot/grub/menu.lst

from

defoptions=quiet splash

to

defoptions=quiet splash noapic nolapic pci=noacpi

I will try this after hours tonight.

I certainly do not need ACPI on this server.

I was able to insert these noacpi options by editing the commented out
kopt= parameter and rerunning update-group. Booted with all ACPI
disabled.

I will see how it goes.

# kopt=root=UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx ro noapic nolapic pci=noacpi acpi=off

So far it seems that the server is running OK, but only time will
tell.
