Thanks Yinghai. It looks like the slot I was using didn't supported the Hotplug. However, then I moved to another slot which did supported Hotplug+ but didn't supported surprise- removal. Here is the tree of my devices. -[0000:00]-+-00.0 +-02.0-[01]--+-00.0 | \-00.1 +-04.0-[02]----00.0 +-09.0-[03]----00.0 +-11.0 +-12.0 +-12.2 +-13.0 +-13.2 +-14.0 +-14.1 +-14.2 +-14.3 +-14.4-[04]-- +-14.5 +-15.0-[05]--+-00.0 | \-00.1 +-16.0 +-16.2 +-18.0 +-18.1 +-18.2 +-18.3 \-18.4 Here is the info on the slot - 00:15.0 PCI bridge: ATI Technologies Inc SB700/SB800/SB900 PCI to PCI bridge (PCIE port 0) (prog-if 00 [Normal decode]) 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- --- BridgeCtl: Parity- SERR- NoISA- VGA- MAbort- >Reset- FastB2B- PriDiscTmr- SecDiscTmr- DiscTmrStat- DiscTmrSERREn- ---- SltCap: AttnBtn- PwrCtrl- MRL- AttnInd- PwrInd- HotPlug+ Surpise- Slot # 0, PowerLimit 0.000000; Interlock- NoCompl+ SltCtl: Enable: AttnBtn- PwrFlt- MRL- PresDet- CmdCplt- HPIrq- LinkChg- Control: AttnInd Unknown, PwrInd Unknown, Power- Interlock- SltSta: Status: AttnBtn- PowerFlt- MRL- CmdCplt- PresDet+ Interlock- Changed: MRL- PresDet+ LinkState+ Now if I first remove the device from the kernel by issuing "echo 1 > /sys/devices/pci0000:\00/0000\:00\:15.0" I see the device being removed from the kernel. lspci output shows that device no longer existed. Then I physically pull out the device from the slot, and then reinsert the device to the same slot and I issue "echo 1 > /sys/bus/pci/rescan" I only see the bridge device being rescanned but don't see my SATA controller being recognized. ie. devices on secondary side of bus 15 does not appear in lspci output. I also tried "resetting secondary bus" using the bridge control register but of no avail. Any ideas?
