--- Comment #3 from Conrad Meyer <cem at freebsd.org> ---
And the value is 0x5e010600, which is the first 32 bits of an 8? byte
allocation.  We expected to find the value uma_junk, which unless otherwise, is
0xdeadc0de.

The only bits that match 0xdeadc0de are 0x5e010000;  i.e., we've cleared bits
0x80acc0de and set bit 0x600.
