There's almost certainly some problem with my DMA handling somewhere - or perhaps interrupt routing - which is causing the AHCI driver to fail thus: xen_set_ioapic_routing: irq 31 gsi 18 vector 184 ioapic 0 pin 18 triggering 0 polarity 1ahci 0000:00:1f.2: PCI INT C -> GSI 18 (level, low) -> IRQ 31 xen: PCI device 0000:00:1f.2 pin 3 -> irq 31 ahci 0000:00:1f.2: AHCI 0001.0200 32 slots 6 ports 3 Gbps 0x27 impl SATA mode ahci 0000:00:1f.2: flags: 64bit ncq sntf pm led clo pmp pio slum part ems scsi0 : ahci scsi1 : ahci scsi2 : ahci scsi3 : ahci scsi4 : ahci scsi5 : ahci ata1: SATA max UDMA/133 abar m2048@0xff970000 port 0xff970100 irq 31 ata2: SATA max UDMA/133 abar m2048@0xff970000 port 0xff970180 irq 31 ata3: SATA max UDMA/133 abar m2048@0xff970000 port 0xff970200 irq 31 ata4: DUMMY ata5: DUMMY ata6: SATA max UDMA/133 abar m2048@0xff970000 port 0xff970380 irq 31 ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata1.00: qc timeout (cmd 0xec) ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4) ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata1.00: qc timeout (cmd 0xec) ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4) ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata1.00: qc timeout (cmd 0xec) ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4) ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata2.00: ATAPI: HL-DT-ST DVD+/-RW GSA-H73N, B103, max UDMA/100 ata2.00: configured for UDMA/100 ata3: SATA link down (SStatus 4 SControl 300) ata6: SATA link down (SStatus 4 SControl 300) scsi 1:0:0:0: CD-ROM HL-DT-ST DVD+-RW GSA-H73N B103 PQ: 0 ANSI: 5 sr0: scsi3-mmc drive: 48x/48x writer cd/rw xa/form2 cdda tray Uniform CD-ROM driver Revision: 3.20 sr 1:0:0:0: Attached scsi generic sg0 type 5 I'm wondering if you can give me a clue as to what might be failing on the AHCI side to give these symptoms, so I have some idea where I need to fix things in my code?
