AVM A1 (Fritz) card produces interrupts

Applicable to
S.u.S.E. version: 4.4
HiSax version: 1.2 to 1.5

Symptom:

The HiSax modul for either the AVM A1 card or the Elsa cards is loaded and works.

Besides permanent interrupts are released. To be checked by:

cat /proc/interrupts

Cause:

Karsten Keil (keil@temic-ech.spacenet.de) writes about it:

The AVM A1 has an internal time basis that produces these interrupts, and currently I do not know how the switching off is, since AVM does not publish any information.

With the Elsa cards it is exactly the same, but it is already known, how the timer can be switched off. In a HiSax version > 1.5 it will be improved.

Solution:

This is not currently changeable, the overhead should stress the system but not much.
