Hi there, We've had a bit of a chat on the IRC channel today about the M57SLI and how the pci bridge does not seem to be initialized properly under LinuxBIOS. The pci-e bridge is initialized ok - pci-e vga cards work fine; pci vga cards do not.
Here's an lspci of the pci bridge (device 06.0), booted from the proprietary bios: 0000:00:06.0 0604: 10de:0370 (rev a2) (prog-if 01) 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: 0000f000-00000fff Memory behind bridge: fb000000-fb0fffff Prefetchable memory behind bridge: fff00000-000fffff BridgeCtl: Parity- SERR- NoISA- VGA- MAbort- >Reset- FastB2B- Capabilities: [b8] #0d [0000] Capabilities: [8c] #08 [a800] 00: de 10 70 03 07 00 b0 00 a2 01 04 06 00 00 81 00 10: 00 00 00 00 00 00 00 00 00 01 01 20 f0 00 80 02 20: 00 fb 00 fb f0 ff 00 00 00 00 00 00 00 00 00 00 30: 00 00 00 00 b8 00 00 00 00 00 00 00 00 00 00 0a and from linuxbios: 0000:00:06.0 0604: 10de:0370 (rev a2) 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=0 I/O behind bridge: 0000f000-00000fff Memory behind bridge: fff00000-000fffff Prefetchable memory behind bridge: fff00000-000fffff BridgeCtl: Parity+ SERR+ NoISA- VGA- MAbort- >Reset- FastB2B- Capabilities: [b8] #0d [0000] Capabilities: [8c] #08 [a800] 00: de 10 70 03 04 01 b0 00 a2 00 04 06 00 00 81 00 10: 00 00 00 00 00 00 00 00 00 01 01 00 f0 00 80 02 20: f0 ff 00 00 f0 ff 00 00 00 00 00 00 00 00 00 00 30: 00 00 00 00 b8 00 00 00 00 00 00 00 00 00 03 0a Uwe thought that perhaps there was an issue with the IRQ or MP table. I've run getpir and mptable while running the proprietary BIOS, and here's the output: http://ward.vandewege.net/m57sli_mptable.output http://ward.vandewege.net/m57sli_irq_tables.c I've also saved a proprietary and linuxbios dmesg output, since there seems to be something funny going on with the PCI bridge detection - under LinuxBIOS no less than 7 devices show up as PCI bridges, rather than the 2 that show up under the proprietary BIOS. http://ward.vandewege.net/m57sli_dmesg_linuxbios.txt http://ward.vandewege.net/m57sli_dmesg_proprietary.txt Suggestions? Things to try?
