JMB368 IDE controller [197b:2368] Yeah, it looks like it just has a generic subsystem/subvendor ID so we can't tell this thing apart from any other JMicron JMB368 PATA controller. Not sure there is anything we can do here to detect this case automatically. Though, I suppose one other thing we could do is just ignore cable detection results for CompactFlash devices - it seems like many CF adapters get this wrong. If the user really connected a fast CF card with a 40-wire cable, the error handling would probably do the right thing and lower the transfer mode if errors occurred. > Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- > Stepping- SERR+ FastB2B- DisINTx- > Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- > <MAbort- >SERR- <PERR- INTx- > Latency: 0, Cache Line Size: 64 bytes > Interrupt: pin A routed to IRQ 19 > Region 0: I/O ports at 4020 [size=8] > Region 1: I/O ports at 4014 [size=4] > Region 2: I/O ports at 4018 [size=8] > Region 3: I/O ports at 4010 [size=4] > Region 4: I/O ports at 4000 [size=16] > [virtual] Expansion ROM at f2900000 [disabled] [size=64K] > Capabilities: [68] Power Management version 2 > Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA > PME(D0-,D1-,D2-,D3hot-,D3cold-) > Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- > Capabilities: [50] Express (v1) Legacy Endpoint, MSI 01 > DevCap: MaxPayload 128 bytes, PhantFunc 0, Latency L0s <64ns, L1 > <1us > ExtTag- AttnBtn- AttnInd- PwrInd- RBE- FLReset- > DevCtl: Report errors: Correctable- Non-Fatal- Fatal- Unsupported- > RlxdOrd- ExtTag- PhantFunc- AuxPwr- NoSnoop- > MaxPayload 128 bytes, MaxReadReq 512 bytes > DevSta: CorrErr- UncorrErr- FatalErr- UnsuppReq+ AuxPwr- > TransPend- > LnkCap: Port #1, Speed 2.5GT/s, Width x1, ASPM L0s, Latency L0 > <1us, L1 <16us > ClockPM- Surprise- LLActRep- BwNot- > LnkCtl: ASPM Disabled; RCB 64 bytes Disabled- Retrain- CommClk+ > ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt- > LnkSta: Speed 2.5GT/s, Width x1, TrErr- Train- SlotClk+ DLActive- > BWMgmt- ABWMgmt- > Capabilities: [70] MSI: Enable- Count=1/1 Maskable- 64bit- > Address: 00000000 Data: 0000 > Kernel driver in use: pata_jmicron > Kernel modules: pata_jmicron > > -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
