There is a BUG_ON() at xen/arch/x86/physdev.c:169 which appears to be dependent upon guest behavior (should close event channel before un-mapping pirq), rather than on internal hypervisor state. In 2.6.18, this likely goes unnoticed because pci_device_shutdown() only calls all the driver shutdown routines. In newer kernels, however, it also calls pci_msi_shutdown() and pci_msix_shutdown(), which
