Re: [afnog]FreeBSD problem interface again!!!

[antonio at nambu.uem.mz]

Hi Brian,

The interfaces are now getting IRQ 10 and 11 but I still get a problem with the 
interface connected to the internet (xl0). The other interface which is 
connected to the internal net (rl0) is working fine. After I connected the mouse 
the IRQ 12 was no longer allocated to any of the interfaces thus resolving the 
watchdog timeout which was happening to both interfaces when the mouse 
was not present. Are you saying I should disable some other stuff like printer 
port or serial port to make those IRQs available to the interfaces? Actually 
IRQ 5 is available but none of the interfaces gets it. IS there a way of making 
an interface get a specific IRQ in FreeBSD? What happens now is that the 
internet interface works only for a few minutes and then stops and I can only 
get it going by doing a  /etc/netstart. Could it be another kind of problem?

Cheers,
