http://perforce.freebsd.org/chv.cgi?CH=131455 Change 131455 by jb@jb_freebsd1 on 2007/12/23 04:34:32 Add a SYSINIT to the end of the SI_SUB_SMP to initialise the cyclic device on the APs just launched. If the cyclic device is loaded after the kernel is booted, this isn't necessary because all the CPUs are listed in the pcpu list. It's only in the case where the cyclic device is loaded by the boot loader that it will be initialised on cpu0 well before and APs are launched.
