General hardware problems

Symptom:

One ore more of the following phenomena occur :

Cause:

These strange phenomenona are most probably down to faulty or wrongly 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 is stable under DOS or Windows, for example, this doesn't say anything about 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 in linear mode with 32 bit bursts, errors can occur.

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

The cause lies quite clearly, then, with the hardware, and not with Linux.

Linux requires more hardware stability than other operating systems do. On the one hand this provides increased performance. On the other hand it can lead to the above mentioned problems on some systems. In contrast to other operating systems Linux assumes that the hardware works properly and is 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 number of parameters and conditions that can be changed in order to isolate the faulty equipment.
