After an upgrade of my Debian Jessie dom0 and domUs, my passthroughed NIC stopped working. This bug was probably introduced in Debian Jessie sometime between 2015-12-30 and 2016-01-08 as 2015-12-30 as 2015-12-30 was the last time I upgraded without any problems according to my dpkg.log. This bug has also been reported to Debian Bug (https://bugs.debian.org/810379), where I got instructions to contact you directly. The Debian Bug List is CC'd to keep the Debian Bug in the loop. I created a new jessie domU (named "bug") and tried to passthrough some PCI devices and found that both USB3 host controller and tg3 NIC generated these lines in domU dmesg: xen:events: Failed to obtain physical IRQ 31 xen:events: Failed to obtain physical IRQ 32 xen:events: Failed to obtain physical IRQ 33 And from the dom0 "xl dmesg": (XEN) mm.c:812: d13: Forcing read-only access to MFN fbff1 (XEN) mm.c:812: d13: Forcing read-only access to MFN fbff1 (XEN) mm.c:812: d13: Forcing read-only access to MFN fbff1 (XEN) mm.c:812: d0: Forcing read-only access to MFN fbff1 (XEN) mm.c:812: d13: Forcing read-only access to MFN faba0 (XEN) mm.c:812: d0: Forcing read-only access to MFN faba0 domU "bug" "lspci -vn": 00:00.1 0200: 14e4:165f     Subsystem: 103c:2133     Flags: bus master, fast devsel, latency 0, IRQ 30     Memory at fabc0000 (64-bit, prefetchable) [size=64K]     Memory at fabb0000 (64-bit, prefetchable) [size=64K]     Memory at faba0000 (64-bit, prefetchable) [size=64K]     Expansion ROM at <ignored> [disabled]     Capabilities: [48] Power Management version 3     Capabilities: [50] Vital Product Data     Capabilities: [58] MSI: Enable- Count=1/8 Maskable- 64bit+     Capabilities: [a0] MSI-X: Enable+ Count=17 Masked-     Capabilities: [ac] Express Endpoint, MSI 00     Capabilities: [100] Advanced Error Reporting     Capabilities: [13c] Device Serial Number 00-00-34-64-a9-9a-a8-b1     Capabilities: [150] Power Budgeting <?>     Capabilities: [160] Virtual Channel     Kernel driver in use: tg3 00:01.0 0c03: 1912:0014 (rev 03) (prog-if 30 [XHCI])     Subsystem: 103c:1996     Flags: bus master, fast devsel, latency 0, IRQ 29     Memory at fbff0000 (64-bit, non-prefetchable) [size=8K]     Capabilities: [50] Power Management version 3     Capabilities: [70] MSI: Enable- Count=1/8 Maskable- 64bit+     Capabilities: [90] MSI-X: Enable+ Count=8 Masked-     Capabilities: [a0] Express Endpoint, MSI 00     Capabilities: [100] Advanced Error Reporting     Capabilities: [150] Latency Tolerance Reporting     Kernel driver in use: xhci_hcd domU "bug" "cat /proc/interrupts":      ÂCPU0    Â16:   Â25114 Âxen-percpu-virq   Âtimer0 Â17:     Â0 Âxen-percpu-ipi    resched0 Â18:     Â0 Âxen-percpu-ipi    callfunc0 Â19:     Â0 Âxen-percpu-virq   Âdebug0 Â20:     Â0 Âxen-percpu-ipi    callfuncsingle0 Â21:     Â0 Âxen-percpu-ipi    irqwork0 Â22:    Â473  xen-dyn-event   xenbus Â23:     96  xen-dyn-event   hvc_console Â24:    8811  xen-dyn-event   blkif Â25:    Â255  xen-dyn-event   blkif Â26:    3045  xen-dyn-event   eth0-q0-tx Â27:    5650  xen-dyn-event   eth0-q0-rx Â28:     93  xen-dyn-event   pcifront Â31:     Â0 Âxen-pirq-pcifront-msi-x Âxhci_hcd Â32:     Â0 Âxen-pirq-pcifront-msi-x Âxhci_hcd Â33:     Â0 Âxen-pirq-pcifront-msi-x Âeth1 NMI:     Â0  Non-maskable interrupts LOC:     Â0  Local timer interrupts SPU:     Â0  Spurious interrupts PMI:     Â0  Performance monitoring interrupts IWI:     Â0  IRQ work interrupts RTR:     Â0  APIC ICR read retries RES:     Â0  Rescheduling interrupts CAL:     Â0  Function call interrupts TLB:     Â0  TLB shootdowns TRM:     Â0  Thermal event interrupts THR:     Â0  Threshold APIC interrupts MCE:     Â0  Machine check exceptions MCP:     Â0  Machine check polls HYP:   Â43966  Hypervisor callback interrupts ERR:     Â0 MIS:     Â0 domU "bug" "dmesg": [  Â0.000000] Initializing cgroup subsys cpuset [  Â0.000000] Initializing cgroup subsys cpu [  Â0.000000] Initializing cgroup subsys cpuacct [  Â0.000000] Linux version 3.16.0-4-amd64 (debian-kernel at lists.debian.org) (gcc version 4.8.4 (Debian 4.8.4-1) [  Â0.000000] Command line: root=/dev/xvda2 ro elevator=noop root=/dev/xvda2 ro [  Â0.000000] ACPI in unprivileged domain disabled [  Â0.000000] 1-1 mapping on 8000->100000 [  Â0.000000] Set 1015808 page(s) to 1-1 mapping [  Â0.000000] 1-1 mapping on 100000->8000000 [  Â0.000000] e820: BIOS-provided physical RAM map: [  Â0.000000] Xen: [mem 0x0000000000000000-0x000000000009ffff] usable [  Â0.000000] Xen: [mem 0x00000000000a0000-0x00000000000fffff] reserved [  Â0.000000] Xen: [mem 0x0000000000100000-0x0000000007ffffff] usable [  Â0.000000] Xen: [mem 0x0000000008000000-0x00000000f1de3fff] unusable [  Â0.000000] Xen: [mem 0x00000000f1de4000-0x00000000f1dedfff] ACPI data [  Â0.000000] Xen: [mem 0x00000000f1dee000-0x00000000f7ffffff] reserved [  Â0.000000] Xen: [mem 0x00000000fec00000-0x00000000feefffff] reserved [  Â0.000000] Xen: [mem 0x00000000ff800000-0x00000000ffffffff] reserved [  Â0.000000] NX (Execute Disable) protection: active [  Â0.000000] DMI not present or invalid.
