Hi The patch d7b830013f59cf586c1cec3caa1ce7156da59a13, committed to 3.17-rc1, breaks the SATA controller (sata_svw driver) on HT1000 ServerWorks chipset. The other drivers work correctly.
With the patch d7b830013f59cf586c1cec3caa1ce7156da59a13, the SATA controller times out after every command with lost interrupt. With the patch 16ee7b3dcc56be14b9a813612cff2cc2339cdced, the SATA driver can't be loaded at all, it fails with: sata_svw 0000:01:0e.0: version 2.3 Failed to set pin attr for GSI11 sata_svw 0000:01:0e.0: PCI INT A: failed to register GSI sata_svw: probe of 0000:01:0e.0 failed with error -1 /proc/interrupts: # cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 CPU4 CPU5 CPU6 CPU7 CPU8 CPU9 CPU10 CPU11 0: 26 0 0 0 0 0 0 0 0 0 0 0 IO-APIC-edge timer 1: 12 0 0 0 0 0 0 0 0 0 0 0 IO-APIC-edge i8042 4: 14 0 0 0 0 0 0 0 0 0 0 0 IO-APIC-edge serial 6: 3 0 0 0 0 0 0 0 0 0 0 0 IO-APIC-edge floppy 8: 0 0 0 0 0 0 0 0 0 0 0 0 IO-APIC-edge rtc0 9: 0 0 0 0 0 0 0 0 0 0 0 0 IO-APIC-fasteoi acpi 11: 350 0 0 0 0 0 0 0 0 0 0 0 IO-APIC-fasteoi sata_svw 14: 0 0 0 0 0 0 0 0 0 0 0 0 IO-APIC-edge pata_serverworks 15: 0 0 0 0 0 0 0 0 0 0 0 0 IO-APIC-edge pata_serverworks 16: 0 0 0 0 0 0 0 0 0 0 0 0 IO-APIC-fasteoi ohci_hcd:usb2, ohci_hcd:usb3, ohci_hcd:usb4 17: 0 0 0 0 0 0 0 0 0 0 0 0 IO-APIC-fasteoi ehci_hcd:usb1 20: 2041 0 0 0 0 0 0 0 0 0 0 0 IO-APIC-fasteoi eth3 28: 6375 0 0 0 0 0 0 0 0 0 0 0 IO-APIC-fasteoi ioc0 NMI: 0 0 0 0 0 0 0 0 0 0 0 0 Non-maskable interrupts LOC: 3651 2122 2022 1639 1125 1065 602 1642 3581 3789 903 792 Local timer interrupts SPU: 0 0 0 0 0 0 0 0 0 0 0 0 Spurious interrupts PMI: 0 0 0 0 0 0 0 0 0 0 0 0 Performance monitoring interrupts IWI: 254 197 252 69 41 32 16 344 324 76 34 19 IRQ work interrupts RTR: 0 0 0 0 0 0 0 0 0 0 0 0 APIC ICR read retries RES: 2609 4492 2614 1944 1328 1048 2050 3602 2280 1557 973 928 Rescheduling interrupts CAL: 77 118 113 115 109 113 368 727 772 706 218 252 Function call interrupts TLB: 39 682 186 83 66 32 19 1232 212 112 97 43 TLB shootdowns THR: 0 0 0 0 0 0 0 0 0 0 0 0 Threshold APIC interrupts MCE: 0 0 0 0 0 0 0 0 0 0 0 0 Machine check exceptions MCP: 2 2 2 2 2 2 2 2 2 2 2 2 Machine check polls ERR: 0 MIS: 0 lspci: 01:0e.0 RAID bus controller: Broadcom BCM5785 [HT1000] SATA (Native SATA Mode) (prog-if 05) Subsystem: Broadcom BCM5785 [HT1000] SATA (Native SATA Mode) Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 64 Interrupt: pin A routed to IRQ 11 Region 0: I/O ports at 9c00 [size=8] Region 1: I/O ports at 9880 [size=4] Region 2: I/O ports at 9800 [size=8] Region 3: I/O ports at 9480 [size=4] Region 4: I/O ports at 9400 [size=16] Region 5: Memory at fa3fe000 (32-bit, non-prefetchable) [size=8K] Expansion ROM at fa3c0000 [disabled] [size=128K] Capabilities: [60] PCI-X non-bridge device Command: DPERE- ERO- RBC=512 OST=8 Status: Dev=01:0e.0 64bit+ 133MHz+ SCD- USC- DC=simple DMMRBC=512 DMOST=8 DMCRS=32 RSCEM- 266MHz- 533MHz- Capabilities: [90] 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: [a0] MSI: Enable- Count=1/1 Maskable- 64bit- Address: 00000000 Data: 0000 Kernel driver in use: sata_svw Mikulas -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
