hifn errors on console

[Eric W. Bates]

I'm running pfsense (an embedded FreeBSD 6.1) on a wrap2C.  I recently
added a Soekris vpn1411 and am now getting infrequent errors:

hifn0: rndtest: ones interval 4 failed (382, 251-373)
hifn0: rndtest: ones interval 1 failed (2663, 2343-2657)
hifn0: rndtest: zeros interval 5 failed (206, 111-201)
hifn0: rndtest: ones interval 2 failed (1385, 1135-1365)
hifn0: rndtest: zeros interval 3 failed (718, 542-708)
hifn0: rndtest: zeros interval 4 failed (243, 251-373)
hifn0: rndtest: zeros interval 3 failed (717, 542-708)

IPSec works fine.  However, I do not know how to tell whether the hifn
is being used.

I had no luck with Google.  Can anyone enlighten me?

Thanks
