 I had a similar problem recently. Fail-over from one NIC to the other
was unreliable. Sometimes I get a few packets lost and then ping would
resume. On more than one occasion fail-over never happened.
 The server in question for me was an IBM x3850 with two Broadcom NICs
onboard using the tg3 drivers and six Intel NICs using the e1000
drivers. RHEL 5.1 was fully up to date.
 An interesting observation here was that bonding never worked reliably
if I had a mixed bag of slave devices, i.e. one Broadcom and one Intel.
Alternatively, I tried using Intel NICs for both slaves with similar
results. Fail-over worked as expected only when I used both the onboard
Broadcom NICs as slaves.
 I think it's a problem with the Intel drivers. I tried again on a
different but identical server earlier today with the same results. Has
anybody else noticed something along the same lines? Should I file a
bugzilla for this?
