You need ACPI or APM for soft power-down.

Tnx James

I have moved the additional card to another PCI slot, but behaviour is 
similar with same warnings/errors at start-up in var/log/messages and dmesg

I made also a trial stopping iptables and trying to connect with the SMP 
kernel (and no acpi=ht option) but no connection established.

Now I have the following options:

1) use the standard kernel
2) use the SMP kernel with no internet connection (!!!!!)
3) use the SMP kernel with acpi=ht option at boot-time but no soft power-off

Of course option 2 is out of discussion

Shall I file a bug???
