Mam sobie maszynke (słaby routerek, 3 sieciówki).
Postanowiłem zainstalować tam iptables, a co za tym idzie 2.4.19 kernelka.

[root w n48 radek]# rpm -qa | grep kernel
kernel-2.4.19-2.8

No i co mam (wycinek dmesg'a) :

Oczywiście system wspiera PCI, ma na PCI 3 sieciówki które działają cały 
czas na wcześniejszym :

I tutejsze dmesg wygląda tak :

Dziwne jest to :

Jak widzicie Host, ISA i IDE mają "Unknown vendor, Unknown device".
Dodam ze na 2.4.19 system wstaje (IDE sie podnosi i moduł ładuje bez 
problemów) lecz nie da się załadować sieciówek (logiczne skoro nie ma 
PCI). Chipset jest tu chyba problemem (na scalaku widnieje jakieś VA), ale 
jeśli wcześniejszy kernel wspierał to późniejsze jajeczko też powinno.



pozdrawiam weekendowo,
