RHES3 + PSP-7.40 = bonding problems

[CA1348593]

Recently I installed a DL380 G4 with Red Hat ES 3 and the latest psp from hp (version 7.40). The network was configured with bonding (active-backup) and vlans but I had problems with the bonding. When the bonding actives the eth0 it doesn't work the network but when the eth1 is active the network works well. I've configured the vlans without bonding in both ethernets and works well in both cases. Finally, discarding hardware problems or switch problems, I have reinstalled bonding drivers from the redhat kernel and reconfigured bonding. The result is that the bonding works well with both ethernets. Is someone having similar problems with the latest psp? I have tried with another machine (same model) with the same results.
