I'm asking because I updated my NAS on the 4th of March from 8-STABLE r225723 to r232477 and am now seeing 157,000 interrupts per second on irq 16 where my SuperMicro AOC-USAS2-L8i resides (this card uses the LSI SAS2008 chip). More details are in a thread on the freebsd-stable mailing list entitled "157k interrupts per second causing 60% CPU load on idle system". The first message is here: http://www.freebsd.org/cgi/getmsg.cgi?fetch=152290+156717+/usr/local/www/db/text/2012/freebsd-stable/20120325.freebsd-stable If this new driver isn't in 8-STABLE yet I think I'll try upgrading the whole system to 9-STABLE.
