Problem with IBM Token Ring Adapter

I have recompiled my kernel using the 2.0.32 source. It seems to have compiled fine axcept I keep getting strange consolde messages continuously throughout my root login sessions. Here is the message:

tr0: Line errors 01, Internal errors 00, Burst errors 00
A/C errors 00, Abort delimeters 00, Lost frames 00
Receive congestion count 00, Frame occupied errors 00
Frequency errors FF, token errors 00

The machine is a dual pentium 200 mmx tyan mboard, ibm auto 16/4 ISA network card (irq 2 0A20-0A23), awe64 sound board (irq 5, 220, dma 1 & 5), matrox mill 2 vid board, 64 meggers of ram.

The network connections appears to work correctly albeit the erros, but I have not tested it too much such as ping etc...

Any help is greatly appreciated,

p.s. Also, I noticed on this older kernel it does not tell you it is a multi processor kernel, how do you make sure the kernel compiled to use both cpus? I know the newer 2.1.x kernles specifically say multiprocessor kernel upon boot up.

First I'd advise you to set the Token Ring card to IRQ 10, IRQ 2 is a bit confusing.

But your really comes to down to:

Your Token Ring adapter has IO-adres A20 (binary 1010 0010 0000)
Your sound card has adres 220 (binary 0010 0010 0000)

As you can see, the bit pattern is the same except for the highest 12th bit. As it happens, this bit isn't used, only bit 0 - 10 are used. So both addresses map to the same IO-adres and you have a conflict.

So just set the soundcard to some other value like 0x240.

This solved a similar problem on a Windows '95 PC, I don't know how modern PC's with PCI-bus etc. handle IO, but that shouldn't matter since the cards used are older).
