Current method of dumping a processor?

[Greg 'groggy' Lehey]

I've tried it on kernels built in January, May and yesterday.  In each
case, I did:

  dumpon /dev/ad0s2b

(for appropriate values of ad0s2b).  All kernels include ddb.  I
entered the debugger with ctrl-alt-esc and entered "panic".  The
kernel from January dumps just fine.  The kernels from May and August
hang.

Am I doing something wrong?  Has something else changed?  Does anybody
else have this problem?
