Current Xen IPI setup functions require that the caller provide a device in order to obtain the name of the interrupt from it. With early AP startup this device is no longer available at the point where IPIs are bound, and a KASSERT would trigger: panic: NULL pcpu device_t cpuid = 0 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xffffffff82233a20 vpanic() at vpanic+0x186/frame 0xffffffff82233aa0 kassert_panic() at kassert_panic+0x126/frame 0xffffffff82233b10 xen_setup_cpus() at xen_setup_cpus+0x5b/frame 0xffffffff82233b50 mi_startup() at mi_startup+0x118/frame 0xffffffff82233b70 btext() at btext+0x2c Fix this by no longer requiring the presence of a device in order to bind IPIs, and simply use the "cpuX" format where X is the CPU identifier in order to describe the interrupt.
