Linus,
Here is a small patch which is needed on non-i386 platforms.
base_addr in ifmap allows one to specify as a kernel boot argument the
base io addr of the net device. It is currently defined as u_short.
However, on a non-i386 platforms, this addr can be greater than what
u_short can

Do we know exactly what userland apps/libs use ifmap? Maybe the
damage is not so bad, so that we can fix this problem without
making it look worse.

I am running Linux v2.4-test5 on MIPS (NEC DDB5476). I got the above
run-time BUG report. See the call stack below. Can someone shed a
light on this problem? Thanks.

This is a weird problem that I am looking at right. It seems to indicate a
bug in the nfs server.
I have a MIPS machine that boots from a NFS root fs hosted on a redhat 6.2
workstation. Everything works fine except that after a few reboots I start to
see the error messages like the following:
