"Shades of PCI Bridge troubles Batman, it looks like the Riddles has returned!"
Strange listing:
a) PCI Bus #1 is missing.
b) Bus 0 - devices 0-5 are missing
It might be good to post back the output of pci -vv but trim it to
show on'y the PCI-PCI bridges. For instance here's one bridge in my
problematic machine:
0000:00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev c2)
(prog-if 00 [Normal decode])
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop-
ParErr- Stepping- SERR+ FastB2B-
Status: Cap- 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort-
<TAbort- <MAbort- >SERR- <PERR-
Latency: 0
Bus: primary=00, secondary=01, subordinate=01, sec-latency=32
I/O behind bridge: 00009000-00009fff
Memory behind bridge: f8000000-f9ffffff
Prefetchable memory behind bridge: f0000000-f7ffffff
BridgeCtl: Parity- SERR+ NoISA+ VGA- MAbort- >Reset- FastB2B-
The 'Bus:' section let's us see which bridges are creating the network
on the way to the video device.
