linux 2.6.15 breaks route to outside world?

hi

running fedora 2 with 2.6.13 on my machine which can communicate with
the outside world just fine.

however, i built the 2.6.15 and when the eth0 device is brought up i am
told:

RTNETLINK answers: No such device
RTNETLINK answers: Network is unreachable
RTNETLINK answers: Invalid argument
RTNETLINK answers: Invalid argument

and this results with routes to the outside world not being setup -- i
can still get to the machines on the local network (192.168.0.x).
rebooting back to 2.6.13 does not have show this issue and the routes
are correctly setup.

i tracked down the first error (No such device) to be generated from
the command

ip route replace 192.168.0.0/24 dev eth0

is there some additional config i need to do with the new kernel and
fc2? i have a fedora 4 machine with the 2.6.15 kernel and this works
fine.
thanks

Any progress with this?

I have the same problem under FC4.

Appears to be a compiler-kernel bug.
I had the problem with FC4 compiled with gcc-4.0.1.
Compiling with gcc-4.0.2-8.fc4 and with the kernel
option "Optimize for size" turned off fixed it for me.

I am running the vanilla 2.6.15 kernel on FC3 without problems.
It is running as an Internet gateway with Masquerading / NAT.

works when i build 2.6.15 using gcc 4.0.1 when "Optimize for size" is
off -- only change i made to the non working setup
