asterisk users - May 2004 - NMI occures while loading the zaptel module

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello,

We are on a point, where we have no further "soft" options to resolve
the
following problem:

While loading the zaptel and wct4xxp module, the following NMI occures:

Uhhuh. NMI received. Dazed and ... You probably have a hardware problem with 
your RAM chips.

The NMI is not a real problem, asterisk just starts fine and everything is ok 
so far. But we are running diagnostic software from HP to detect hardware 
problems. And this software produces a kernel panic because of this NMI from 
the zaptel module. We can observe this NMI on two machines of the same type 
and software configuration.

Hardware:
HP DL380 G3, 1024 MB RAM, 2x Xeon 3.2 Ghz

Software:
RedHat Linux 7.3 Professional, the whole bunch of HP Software

What we have done so far:
- - tried kernel version 2.4.18-3, 2.4.25, 2.4.26
- - tried zaptel stable and latest
- - disabling HyperThreading in BIOS
- - removed the second processor
- - run memtest86 for about 7 hours - no problems
- - disabling SMP support in the kernel
- - enabled/disabled APIC-Support
- - contacted support at digium, they say it is a problem in the kernel, not a 
problem with their module


I have no idea except, change the operating system or the hardware or fix the 
software bug - if it is a software bug.

Any hints, advices?
