I have been ill :-(. All the error messages stem from kernel 3.11.7. In the meantime 3.13.2 became stable for gentoo and I installed that a few days ago. I have not run the debug output yet or timed the shutdown process, but there's still a delay with that kernel and it feels as long as before. I you want, I can clearly provide new debug output or timing information.<NOTE: at this point a 10s pause happens> libxl: error: libxl_device.c:1134:libxl__wait_for_backend_deprecated: Backend /local/domain/0/backend/pci/4/0 not ready (state 7) libxl: error: libxl_device.c:1138:libxl__wait_for_backend_deprecated: FE /local/domain/4/device/pci/0 state 6 libxl: debug: libxl_pci.c:204:libxl__device_pci_remove_xenstore: pci backend at /local/domain/0/backend/pci/4/0 is not ready libxl: error: libxl_pci.c:1250:do_pci_remove: xc_domain_irq_permission irq=16So the backend here is in state 7 (Reconfiguring), but the frontend is in state 6 (Closed). I think this is a bug in pciback. I looked at drivers/xen/xen-pciback/xenbus.c in Linux 3.13 and found xen_pcibk_frontend_changed which seems to do roughly what I would expect. Has this changed at some point ? Atom, what kernel are you using ? Thanks Atom2 Thanks, Ian. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
