Same here, while trying to upgrade from 5.2.1-RELEASE to yesterday's
and today's -CURRENT. It happens here:

# make installkernel KERNCONF=GENERIC
# reboot   (in single user mode)
# mount -a 
# mergemaster -p
# make installworld
<panic: sleeping without a mutex
at line 144 in file /usr/src/sys/kern/kern_synch.c>

The panic is 100% reproducible.

My work around was to boot kernel.old, then 'make installworld' etc.,
and then reboot (with new kernel). Seems to work so far...
