Hi, I want to assign a DLINK DWA-556 to a virtual machine on a Supermicro C2SBC-Q Board with vt-d enabled. When I start the machinge I get a "freeing invalid memtype" error. I saw the card in the virtual machine and the ath9k driver load without errors, all tools can access the card, but I get no connections or see wlans during iwlist scan. On the host the card works properly. I use qemu-kvm-devel-88 and kvm-kmod-devel-88. Hopefully someone can help me with this problem. regards wolfgang I attached the lspci output from the host and guest. start command: kvm -name router -hda /kvm/router/hda.img -hdb /kvm/router/swap.img -m 256 -net nic,vlan=0,macaddr=52:54:00:12:34:56 -net tap,vlan=0 -curses -pcidevice host=05:00.0 this is the dmesg output on the host. pci 0000:05:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 assign device: host bdf = 5:0:0 pci 0000:05:00.0: irq 33 for MSI/MSI-X pci 0000:05:00.0: irq 33 for MSI/MSI-X kvm:4509 freeing invalid memtype d0300000-d0301000 pci 0000:05:00.0: irq 33 for MSI/MSI-X pci 0000:05:00.0: irq 33 for MSI/MSI-X kvm:4509 freeing invalid memtype d0301000-d0310000 pci 0000:05:00.0: PCI INT A disabled Host Kernel: Linux kvmserver 2.6.30-gentoo-r2 #11 SMP Sat Jul 18 15:27:53 CEST 2009 x86_64 Intel(R) Core(TM)2 Duo CPU E6850 @ 3.00GHz GenuineIntel GNU/Linux Guest Kernel: Linux router 2.6.30 #7 SMP Sat Jul 18 15:53:28 CEST 2009 i686 QEMU Virtual CPU version 0.10.50 GenuineIntel GNU/Linux dmesg output in Guest: ACPI: PCI Interrupt Link [LNKA] enabled at IRQ 10 ath9k 0000:00:05.0: PCI INT A -> Link[LNKA] -> GSI 10 (level, high) -> IRQ 10 ath9k 0000:00:05.0: setting latency timer to 64 phy0: Selected rate control algorithm 'ath9k_rate_control' Registered led device: ath9k-phy0::radio Registered led device: ath9k-phy0::assoc Registered led device: ath9k-phy0::tx Registered led device: ath9k-phy0::rx phy0: Atheros AR5418 MAC/BB Rev:2 AR2133 RF Rev:81: mem=0xd0820000, irq=10 dmesg output testing the card direct on the Host: ath9k 0000:05:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 ath9k 0000:05:00.0: setting latency timer to 64 phy0: Selected rate control algorithm 'ath9k_rate_control' Registered led device: ath9k-phy0::radio Registered led device: ath9k-phy0::assoc Registered led device: ath9k-phy0::tx Registered led device: ath9k-phy0::rx phy0: Atheros AR5418 MAC/BB Rev:2 AR2133 RF Rev:81: mem=0xffffc200011e0000, irq=16
