With this additional _hack_ attached, I was able to restore x86-64 XenLinux with latest bk, and now ACPI works with x86-64 Linux (see below). Keir should fix the bug properly. Basically what's happening is that x86-64 xenlinux cannot access machine-to-phys mapping, which is critical info to the guest. config.h: /* Slot 256: read-only guest-accessible machine-to-phys translation table. */ #define RO_MPT_VIRT_START (PML4_ADDR(256)) #define RO_MPT_VIRT_END (RO_MPT_VIRT_START + PML4_ENTRY_BYTES/2) At this point, as you see, L3 does not have USER bit, and x86-64 XenLinux cannot access it; it used to be able to do that until recently. My hack just adds USER bit upon #PF to L3 (see the patch attaced).
