Error description
Problem Environment: Etherchannel ent14 =ent4 + ent7 Etherchannel ent15 =ent5 + ent6 When booting etherchannel ent14 will get priority to configure over ent15. so the underlying adapters ent4 and ent7 will get first chance of getting configured Because of the frequency of CPU servicing these adapters interrupt with these adapters to be configured. So more number of adapters more number of interrupt generations. And for this reason the chances of Link down will appear more for the adapters configured later. Work around: 1> Reset the switch connected to these adapters. OR 2> re-configure the Etherchannel ( this stays up until next boot)
Local fix
Work around: 1> Reset the switch 2> Reconfigure the etherchannel Both the above workaround will work for until the next reboot.
Problem summary
adpater link may not come up after the reboot.
Problem conclusion
Remove set_port_cfg IDC(Inter Driver Communication) calls made from device open and during mac_address_change which doesnt have any significance.
Temporary fix
