I was having this kind of trouble with my (UP) laptop, but not my (SMP)
build machine.  However, the laptop may also be having some hardware
issues, so I didn't press the issue....  But after getting another panic
after trying to reboot after installing today's -CURRENT on the laptop,
I applied that patch, and so far, things seem better.

What I did:

* Fetched the patch & unzipped it.

* cd /usr/src/sys && patch -p6 <~/PATCHES/procswap.diff
  (I actually ran "patch -C" first, to verify that things looked good.)

* cd /usr/src && make kernel KERNCONF=LAPTOP_30W

* reboot (after a few syncs, in case that might help).

* cd /usr/src && date && make installworld && date && \
  mergemaster -u 0022 -i && date && df -k
  (I.e., re-do the "make installworld & mergemaster steps from the
  install where I had a panic on reboot, both to have some assurance that
  files I'd rather have didn't get truncated, and to serve as a first-
  order test of the patched code.)

* reboot

* Run a few tests.

So far, so good.
