Yesterday, I upgraded the kernel on my sparc64 to -head,
so I was running a mis-matched kernel and userland.
The userland was a recent (as of two days ago) stable/10.
In the nightly report, I noticed the following:

As you can see, the "drop" column for the host has
completely outrageous values.
When representing those numbers as binary, there's
an awful lot of zeros in the low order bits, like
some structure is being referenced off by a word or
two.

I also find it more than slightly curious that the "drop" values for
bge0 and lo0 are identical.
Do we have some subtle ABI differences between the two systems
(stable/10 vs -head)?
