that should not work. as pciehp will not be loaded for 00:03.0 with
following slot cap
SltCap: AttnBtn- PwrCtrl- MRL- AttnInd- PwrInd- HotPlug- Surpise-
Slot # 2, PowerLimit 25.000000; Interlock- NoCompl-
but 04:08.0, 06:04.0, 06:0c.0, 06:08.0 and 06:10.0 do have
SltCap: AttnBtn+ PwrCtrl+ MRL+ AttnInd+ PwrInd+ HotPlug+ Surpise-
Slot # 4, PowerLimit 25.000000; Interlock- NoCompl-
problem is
1. pciehp is not loaded for them.
2. fpga are on 06:07.0 and 06:0e.0.
If 04:08.0 pciehp could be loaded, the could use that hotplug to make
fpga working
