New submission from Antonio Huete Jimenez <tuxillo at quantumachine.net>:


My Asus M2N4-SLI motherboard equiped with an Athlon X2 has an it(4) hardware 
monitor chip. 

It seems that it stops the fan every 10-12 seconds and restart it every 7-8 
seconds or so. I've tested in others Operating Systems I have installed on that 
machine (linux) and the fan is not stopping at any time, so I think there must 
be any issue under DFBSD.
