Problemas com Modem e kernel 2.6
Pessoal,
tenho um hardmodem USRobotics. No kernel 2.4 ele funciona beleza, mas no
kernel 2.6.x ele da o seguinte erro:
[root@zeus ~]# wvdial
--> WvDial: Internet dialer version 1.54.0
--> Cannot open /dev/ttyS4: Input/output error
--> Cannot open /dev/ttyS4: Input/output error
--> Cannot open /dev/ttyS4: Input/output error
Olhando o lspci, observei que o modem e a placa de vídeo tem o mesmo IRQ, mas
isto muda entre o kernel 2.4 e 2.6, veja:
lspci do kernel 2.4.x:
0000:00:11.0 Serial controller: 5610 56K FaxModem 56K FaxModem

lspaci do kernel 2.6.11:

Já tentei recompilar o kernel 2.6.11 mas mesmo assim o modem não funciona.
Alguem tem alguma solução para isto? O que pode ser o problema?
Valeu
