How to repeat symptoms: boot -c <make some changes, quit and come up normally> kget
Watch your system panic when kget does a: sysctlbyname("machdep.uc_devlist", buf, &len, NULL, NULL); where len has been properly fetched in a previous syctlbyname() call (1526 bytes, in my test case) and buf allocated appropriately. System will panic with a supervisor read, page not present. In fact, I've just proven the hard way that trying to read machdep.uc_devlist in any way, including sysctl -a, does the same thing.
