There are three problems which could explain this...

- an odd problem in bond routing in U4 + U5 kernels.
- a problem with the e1000 driver with multiple NICs in bonded mode
which causes "ifconfig" to fail spuriously.
- a bug with clumanager versions < re: bonded IPs.

I think it's one of the first two, or a combination of both.

The new ( version of clumanager is available on RHN.
Unsupported test kernels which should fix the first two issues are
available here:


You can also try downgrading the initscripts package to the GA version
to work around the regression in bond routing.  If neither solve your
problem, please file a ticket with Red Hat Support:
