I have a system setup with IP bonding.
The NIC cards are 1gig,
but sometimes, not always, I get this error ( below )
which makes the NICs into 100Mbps.
( observed on the RH 4 Update 4 system. )
Anybody know why ?

On my server, the link speed cannot be detected at first but is set to
1000Mbps just after :
