Quoting Tom Sylla tsylla@gmail.com:
Those bits *mean* something. You seem to be having parity or system errors on that PCI segment. You need to figure out why. I assume that with the factory BIOS you do not get serr or perr secondary status reported?
Here is the lspci-vvv from the PCI Bridge: 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 82) (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=64 I/O behind bridge: 0000c000-0000cfff Memory behind bridge: ff700000-ff7fffff Prefetchable memory behind bridge: fff00000-000fffff Secondary status: 66MHz- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort+ <SERR- <PERR- BridgeCtl: Parity- SERR+ NoISA+ VGA- MAbort- >Reset- FastB2B-
It does not appear to have any parity error checking enabled. Here is lspci -xxx:
