IRQ assignment in 2.2 vs. 2.4 kernels

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi, everyone -

I have a question about IRQ assignment. I'm running on an ABIT SR7-8X, 
which is a newer Pentium IV motherboard that supports ACPI. The board as 
an integrated RTL8139 Ethernet controller. When I boot under a 2.2 
series kernel (the Debian Woody installation kernel), it assigns eth0 
IRQ 11. It does the same when booting under Windows ME. When I boot 
under 2.4.18, though, it puts eth0 at IRQ 19 and moves USB up to the 
20-22 range. Needless to say, Ethernet stops working at that point. :-)

So I guess my first question is how can I go about diagnosing where the 
IRQ mis-assignment is coming from? I've already set "Plug and Play OS" 
to "no". Is there something that's changed between the 2.2 and 2.4 
kernels that might be getting confused here?

thanks very much,
Jeff
