"echo" helps nothing in this issue, the /dev/scd1 still can not appear, Here is the log message when do "echo", ata2 is the new SATA port connected to SATA HDD after hotplug under native IDE mode: ================================================ Dec 21 00:38:00 linux-d8vg kernel: ata2: soft resetting link Dec 21 00:38:00 linux-d8vg kernel: ata2: SATA link down (SStatus 0 SControl 300) Dec 21 00:38:00 linux-d8vg kernel: ata2: EH complete > Also, after driver is loaded, can you please post the results of "lspci > -nnvvvxxx" with BIOS mode set to IDE and AHCI? There are too much messages, I only keep the SATA controller as below: ========= Native IDE mode ======= 00:11.0 SATA controller [Class 0106]: ATI Technologies Inc SB700 SATA Controller [IDE mode] [1002:4390] (prog-if 01 [AHCI 1.0]) Subsystem: ATI Technologies Inc SB700 SATA Controller [IDE mode] [1002:4390] 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: 64, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 22 Region 0: I/O ports at d000 [size=8] Region 1: I/O ports at c000 [size=4] Region 2: I/O ports at b000 [size=8] Region 3: I/O ports at a000 [size=4] Region 4: I/O ports at 9000 [size=16] Region 5: Memory at fe8ff800 (32-bit, non-prefetchable) [size=1K] Capabilities: [60] 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- Capabilities: [50] Message Signalled Interrupts: Mask- 64bit+ Queue=0/2 Enable- Address: 0000000000000000 Data: 0000 Capabilities: [70] #12 [0010] 00: 02 10 90 43 07 01 30 02 00 01 06 01 10 40 00 00 10: 01 d0 00 00 01 c0 00 00 01 b0 00 00 01 a0 00 00 20: 01 90 00 00 00 f8 8f fe 00 00 00 00 02 10 90 43 30: 00 00 00 00 60 00 00 00 00 00 00 00 0b 01 00 00 40: 10 00 3a 20 01 00 10 00 00 00 00 01 00 00 00 00 50: 05 70 84 00 00 00 00 00 00 00 00 00 00 00 00 00 60: 01 50 22 00 00 00 00 00 00 00 00 00 00 00 00 00 70: 12 00 10 00 0f 00 00 00 00 00 00 00 00 00 00 00 80: 00 00 00 00 06 00 00 2c 16 80 b4 01 16 80 b4 01 90: 16 80 b4 01 16 80 b4 01 16 80 b4 01 16 80 b4 01 a0: 7a a0 7a a0 7a a0 7a a0 7a a0 7a a0 00 00 00 00 b0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 c0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 d0: 00 00 00 00 00 00 00 00 00 00 00 00 00 20 00 00 e0: 80 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 f0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ========= AHCI mode ======= 00:11.0 SATA controller [Class 0106]: ATI Technologies Inc SB700 SATA Controller [AHCI mode] [1002:4391] (prog-if 01 [AHCI 1.0]) Subsystem: ATI Technologies Inc SB700 SATA Controller [AHCI mode] [1002:4391] 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: 64, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 22 Region 0: I/O ports at d000 [size=8] Region 1: I/O ports at c000 [size=4] Region 2: I/O ports at b000 [size=8] Region 3: I/O ports at a000 [size=4] Region 4: I/O ports at 9000 [size=16] Region 5: Memory at fe8ff800 (32-bit, non-prefetchable) [size=1K] Capabilities: [60] 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- Capabilities: [50] Message Signalled Interrupts: Mask- 64bit+ Queue=0/2 Enable- Address: 0000000000000000 Data: 0000 Capabilities: [70] #12 [0010] 00: 02 10 91 43 07 01 30 02 00 01 06 01 10 40 00 00 10: 01 d0 00 00 01 c0 00 00 01 b0 00 00 01 a0 00 00 20: 01 90 00 00 00 f8 8f fe 00 00 00 00 02 10 91 43 30: 00 00 00 00 60 00 00 00 00 00 00 00 0b 01 00 00 40: 10 00 00 20 01 00 10 00 00 00 00 01 00 00 00 00 50: 05 70 84 00 00 00 00 00 00 00 00 00 00 00 00 00 60: 01 50 22 00 00 00 00 00 00 00 00 00 00 00 00 00 70: 12 00 10 00 0f 00 00 00 00 00 00 00 00 00 00 00 80: 00 00 00 00 06 00 00 2c 16 80 b4 01 16 80 b4 01 90: 16 80 b4 01 16 80 b4 01 16 80 b4 01 16 80 b4 01 a0: 7a a0 7a a0 7a a0 7a a0 7a a0 7a a0 00 00 00 00 b0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 c0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 d0: 00 00 00 00 00 00 00 00 00 00 00 00 00 20 00 00 e0: 80 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 f0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Thanks Shane - 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
