Unfortunately it doesn't fix the second symptoms with pci-passthrough, the device still doesn't receive irq's on intel and the video device still haas issues on AMD. What i have tested extensively and works stable for me is: david's patch + revert of cffe0a2b5a34c95a4dadc9ec7132690a5b0f6687 "x86, irq: Keep balance of IOAPIC pin reference count" Hope that helps in finding the solution. -- Sander > Jiang Liu (2): > xen/pci: Kill function xen_setup_acpi_sci() > xen/pci: Simplify x86/pci/xen.c by killing gsi_override related code > arch/x86/kernel/acpi/boot.c | 26 ++++++++--------- > arch/x86/pci/xen.c | 68 > ++++--------------------------------------- > 2 files changed, 19 insertions(+), 75 deletions(-) -- 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/
