I never used the bridging functionality, but would calling a "ifconfig 
br0 down" help ?
You could also try to bring down the "real" interfaces.

It sounds to me like there's a problem with the 8139too driver, you 
probably could check if there's a patch available.
I'm slowly getting ready to release 1.2.1, so if you hurry up we can 
include the patch.

I also saw that 2.4.28-rc3 just got released, check the changelog if 
they mention something there.
