Crash on -current amd64

[Paul Goyette <paul%whooppee.com@localhost>]

I just build a new kernel from current sources (updated just a couple of 
hours ago), and got the following crash during system boot:

panic: kernel diagnostic assertion "cred != NULL" failed: file "..../kern/kern_auth.c", line 266

traceback:

vapnic + 0x140
cd_play_msf +0x0
kauth_cred_geteuid + 0x50
genfs_can_access + 0x28
ufs_access + 0x93
exec_elf64_makecmds + 0x57b
check_exec + 0x3b1
execve_loadvm + 0x247
execve1 + 0x28
start_init + 0x273

Granted, my system is somewhat unusual.  In particular, the exec_elf64 
module is NOT included in the kernel, rather it is auto-loaded when it 
is first needed (ie, when running /sbin/init).  But this set-up has been 
working for years without issue.

Has anything changed recently in this area?

Also note that forcing the bootloader to pre-load the coredump and 
exec_elf64 modules doesn't help - the identical panic occurs.
