Eric,

I have checked the latest code again for Opteron MB. The MB still needs to
reset three times to get it done.

1. Hyper transport scan link: 0 max: 1
PCI: 01:01.0 [1022/7450] enabled next_unitid: 0003
PCI: 01:03.0 [1022/7460] enabled next_unitid: 0007
HyperT reset needed
2. Initializing devices...
PCI: 00:18.3 init
NB: Function 3 Misc Control.. resetting cpu
3. Initializing devices...
PCI: 00:18.3 init
NB: Function 3 Misc Control.. done.
PCI: 00:19.3 init
NB: Function 3 Misc Control.. resetting cpu

Can we only reset the MB only time to make the HT work at the need
speed/width?

I mean only enable the reset in 
PCI: 00:19.3 init
NB: Function 3 Misc Control.. resetting cpu

Regards

YH
