Johan, Can you attach output for lcpci -vv and a boot trace to start with. Thanks. Copying to Kristen, to help sort this out. |
Most recent kernel where this bug did *NOT* occur: none Distribution: Debian unstable Hardware Environment: EPIA MII 12000 Problem Description: Several problems occur with the PCMCIA bridge on this board. I would first get the cs: pcmcia_socket0: unable to apply power. message each time i would plug in a card. The message went away when adding the override_bios=1 option to the yenta module. Now however I am seeing an even stranger behavior. When I plug a PC-Card WLAN adaptor, which is known to work on my laptop, the card reports a wrong value as its device identifier: 0000:02:00.0 0080: 1814:0102 Subsystem: 1186:3c08 Control: I/O- Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=slow >TAbort- <TAbort- <MAbort- >SERR- <PERR+ Interrupt: pin A routed to IRQ 5 Region 0: Memory at <ignored> (32-bit, non-prefetchable) [disabled] Capabilities: <available only to root> The card's description as seen on my laptop is: 05:00.0 0280: 1814:0302 Subsystem: 1186:3c08 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=slow >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 64, Cache Line Size: 32 bytes Interrupt: pin A routed to IRQ 169 Region 0: Memory at aa000000 (32-bit, non-prefetchable) [size=32K] Capabilities: [40] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 PME-Enable- DSel=0 DScale=0 PME- Note the one bit difference in the device ID (0102 / 0302). The memory area seems to be borked too. I have tried adding pci=assign-busses but with no success. The controller is the RL5c476 II (rev 80) which I have read has numerous problems. 0000:00:0a.0 CardBus bridge: Ricoh Co Ltd RL5c476 II (rev 80) Subsystem: VIA Technologies, Inc.: Unknown device aa01 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 168 Interrupt: pin A routed to IRQ 5 Region 0: Memory at de01b000 (32-bit, non-prefetchable) [size=4K] Bus: primary=00, secondary=02, subordinate=05, sec-latency=176 Memory window 0: 10000000-13fff000 (prefetchable) Memory window 1: 14000000-17fff000 I/O window 0: 00001000-000010ff I/O window 1: 00001400-000014ff BridgeCtl: Parity- SERR- ISA- VGA- MAbort- >Reset- 16bInt- PostWrite+ 16-bit legacy interface ports at 0001
