Hi I was able to test Xen 3.4.3-rc3 and the current 2.6.32 tree on a HP DL385 G6. It booted after some time, but was unuable to access several devices using traditional IO-APIC. The interrupt configuration listed for these is identical between Xen and native except that in the native case several of them are marked as "IO-APIC-fasteoi". Devices using MSI are working fine. Partial /proc/interrupts output with comparation of Xen and native: | 5: IO-APIC-fasteoi ehci_hcd:usb1, ohci_hcd:usb3, ohci_hcd:usb4 | 5: xen-pirq-ioapic-edge ehci_hcd:usb1, ohci_hcd:usb2, ohci_hcd:usb4 | 14: IO-APIC-fasteoi sata_svw | 14: xen-pirq-ioapic-edge sata_svw Kernel log showing the setup of this devices: [ 0.000000] xen: registering gsi 5 triggering 1 polarity 0 [ 0.000000] xen: --> irq=5 [ 0.000000] Already setup the GSI :5 [ 0.000000] xen: registering gsi 14 triggering 1 polarity 0 [ 0.000000] xen: --> irq=14 [ 0.000000] Already setup the GSI :14 [ 1.625355] ACPI: PCI Interrupt Link [IUSB] enabled at IRQ 5 [ 1.625594] xen: registering gsi 5 triggering 0 polarity 1 [ 1.625607] xen_allocate_pirq: returning irq 5 for gsi 5 [ 1.625872] xen: --> irq=5 [ 1.625883] Already setup the GSI :5 [ 1.626062] ehci_hcd 0000:00:07.2: PCI INT A -> Link[IUSB] -> GSI 5 (level, low) -> IRQ 5 [ 1.626506] ehci_hcd 0000:00:07.2: EHCI Host Controller [ 1.626805] ehci_hcd 0000:00:07.2: new USB bus registered, assigned bus number 1 [ 1.652169] ehci_hcd 0000:00:07.2: irq 5, io mem 0xf3dc0000 [ 1.717401] sata_svw 0000:01:0e.0: version 2.3 [ 1.718282] ACPI: PCI Interrupt Link [ISF0] enabled at IRQ 14 [ 1.718520] xen: registering gsi 14 triggering 0 polarity 1 [ 1.718533] xen_allocate_pirq: returning irq 14 for gsi 14 [ 1.718747] xen: --> irq=14 [ 1.718754] Already setup the GSI :14 [ 1.718903] sata_svw 0000:01:0e.0: PCI INT A -> Link[ISF0] -> GSI 14 (level, low) -> IRQ 14 [ 1.719514] scsi0 : sata_svw [ 1.719922] scsi1 : sata_svw [ 1.720404] scsi2 : sata_svw [ 1.720739] scsi3 : sata_svw [ 1.720996] ata1: SATA max UDMA/133 mmio m8192@0xf3ff0000 port 0xf3ff0000 irq 14 [ 1.721272] ata2: SATA max UDMA/133 mmio m8192@0xf3ff0000 port 0xf3ff0100 irq 14 [ 1.721536] ata3: SATA max UDMA/133 mmio m8192@0xf3ff0000 port 0xf3ff0200 irq 14 [ 1.721809] ata4: SATA max UDMA/133 mmio m8192@0xf3ff0000 port 0xf3ff0300 irq 14 Kernel log showing interrupt problems on GSI 5: [ 7.452081] ohci_hcd 0000:00:07.1: Unlink after no-IRQ?
