+xhci_kick_epctx: Assertion `ring->dequeue != 0' failed.
+
+To reproduce run the QEMU with the following command line:
+```
+qemu-system-x86_64 -cdrom hypertrash_os_bios_crash.iso -nographic -m 100 -enable-kvm -device virtio-gpu-pci -device nec-usb-xhci -device usb-audio
+```
+
+QEMU Version:
+```
+# qemu-5.0.0
+$ ./configure --target-list=x86_64-softmmu --enable-sanitizers; make
+$ x86_64-softmmu/qemu-system-x86_64 --version
