General hardware problems

Symptom:

One ore several of the following phenomena occur :

Cause:

These strange phenomenons are to be explained for sure either by faulty or extremely sharp configured hardware.

The reason for this is that many motherboards apparently have timing problems. These timing problems become visible through bus errors (CPU-memory-PCI-ISA).

Even if the system works stable under e.g. DOS or Windows, this doesn't mean anything for the stability of the hardware and its configuration. The hardware manages to work with the slow segmentated memory access of a CPU working in 16 bit realmode (under DOS, Windows). As soon as the memory is accessed linear with 32 bit bursts errors can occur.

A further cause can be a badly cooled CPU or too slow or faulty (heat-sensitive) RAM moduls (SIMMS).

So this is for sure caused by the hardware and not by Linux.

Linux requires more hardware stability than other operating systems do. On one hand this way a higher performance can be achieved. On the other hand this can lead to the above mentioned problems on some systems. In contrast to other operating systems Linux assumes that the hardware works stable. If this is not the case Linux stops working.

An operating system that still runs with faulty or potentially faulty hardware represents a severe security risk.

Remedy

There are a couple of parameters and conditions that can be changed in order to isolate the faulty equipment.
