re: Current port status

i've had a new crash.  i saw it with a 5.99.65 kernel and a
very -current kernel, when trying to read a new kernel over NFS
from the build machine:

panic: kernel diagnostic assertion "cur->pcg_avail == cur->pcg_size" failed: file "/usr/src/sys/kern/subr_pool.c", line 2573

saved LR(0x2) is invalid.

not much idea about it yet.  the assert means that because
we've taken the slow path, the cache should be full.  100%
repeatable for me.
