The interrupt timeouts are probably related to the IOMMU errata, the ACPI poweroff problem is because we need to negotiate the shutdown with the hypervisor, which we currently don't do. I have a very hacky patch for FreeBSD that should fix it, but I haven't found time to properly integrate it: http://xenbits.xen.org/gitweb/?p=people/royger/freebsd.git;a=patch;h=612509976d5d2af7633547e0279aae08a6508d7c Leaving this aside, I have a patch for Xen I would like you to try on this box, it *should* fix the INS/OUTS problem (not the poweroff). I've pushed it to a branch on my git repo, you can find it at: http://xenbits.xen.org/gitweb/?p=people/royger/xen.git;a=shortlog;h=refs/heads/pvh_io_ports.v1 or git://xenbits.xen.org/people/royger/xen.git branch pvh_io_ports.v1 If you still get the timeouts please post the full boot log and we can try to figure out if there's any workaround. Thanks, Roger.
