Package: qemu-kvm Version: 1:2.8+dfsg-2~bpo8+1 Severity: normal Tags: patch upstream
Dear Maintainer, qemu-kvm 2.8 (from jessie-backports) has an issue that breaks USB device passthrough to guests. See: https://bugs.launchpad.net/qemu/+bug/1653384 The VM crashes as soon as USB access occurs. This error shows in the libvirt log: qemu-system-x86_64: /build/qemu-m5GCLa/qemu-2.8+dfsg/hw/usb/core.c:619: usb_packet_cleanup: Assertion `!usb_packet_is_inflight(p)' failed. The following patch seems to fix it (taken from the above URL): --- qemu-2.8+dfsg.orig/hw/usb/hcd-xhci.c +++ qemu-2.8+dfsg/hw/usb/hcd-xhci.c @@ -2198,7 +2198,9 @@ static void xhci_kick_epctx(XHCIEPContex xhci_complete_packet(xfer); } assert(!xfer->running_retry); - xhci_ep_free_xfer(epctx->retry); + if (xfer->complete) { + xhci_ep_free_xfer(epctx->retry); + } epctx->retry = NULL; } Thanks! -- System Information: Debian Release: 8.7 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 3.16.0-4-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages qemu-kvm depends on: ii qemu-system-x86 1:2.8+dfsg-2~bpo8+1 qemu-kvm recommends no packages. qemu-kvm suggests no packages. -- no debconf information
