<DIV><FONT face=Arial size=2>With your current setup, your IDE channels,
ethernet card and BRI card are all on seeperate interrupts, so you shouldn't
have problems unless you will be making heavy use of USB devices.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>It appears that you are using an
Intel ICH5 based motherboard. The Intel ICH5 chipset supports IO-APIC. If you
recompile your kernel with IO-APIC support each seperate device will get an
interrupt of its own, and any potential interrupt problems should
disappear.</FONT></DIV>

<DIV><FONT face=Arial size=2>Hello</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am using a Junghanns QuadBRI ISDN card - the
module name is qozap. If I like at my interrupt assignment, qozap is
sharing interrupt 10 with libata and uhci_hcd.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I think libata is the IDE hard drive module and
uhci_hcd is a USB module.</FONT></DIV>
