Yes, this is a known bug in the Intel PCI-Express chipsets. They botched the APIC interrupt masking and it causes interrupt storms to appear on the USB interrupts. The upshot is that you'll have to completely and utterly disable any usb on the system. I'm not sure if this is the cause of this poster's problem though. It certainly will not be helping though. -- Peter Wemm - peter@wemm.org; peter@FreeBSD.org; peter@yahoo-inc.com "All of this is for nothing if we don't go to the stars" - JMS/B5
