The interrupts seem > to come from one of the atapci controllers, apparently atapci0 (main > controller, with a SATA disk and an ATAPI optical drive). I'm a little confused by the kernel output. It appears as if you're using the new SATA-to-CAM layer (ahci.ko) for your SATA disks, rather than the ataahci.ko layer... but I don't see any indication of AHCI being available/used on your southbridge chipset. Possibly this is the source of the problem (specifically, it looks like FreeBSD doesn't have proper device ID knowledge of what this controller is. I believe that's because this system is *very* new, a Core i3/i5/i7 system)? If you disable use of ahci.ko and use the standard ata(4) layer, does the interrupt storm go away? -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
