IRQ Problem !!!

[Shubhangi Jadhav]

Hi,

I got my motherboard to successfully boot with LinuxBIOS. It gets on the
network with both the internet interface up and seems to asign the IRQ
correctly in LinuxBIOS. ping is OK.However when I start a video streaming
application which uses a Multimedia card(encoder)card on a PCI slot, the
network goes out.
    This encoder card uses a fast interrupt and I have read that in such a case
interrupt handlers run with all other interrupts disabled. Was wondering
whether this is what is happening in my case. Is it that the ethernet
interrupts get disabled whenever a fast interrupt comes up and then it is
never enabled again?
    Any suggestions on what could be the possible solution?
