[-- Attachment #1 --] I have an Interrupt load of 2000 interrupts/s from xhci0. As the culprit I have identified the following device: ugen0.6: <vendor 0x8087 product 0x07dc> at usbus0, cfg=255 md=HOST spd=FULL (12Mbps) pwr=ON (100mA) The impression I have from googling this is that it's an unsupported BT device sitting on board of my Intel Wireless AC 7260 card (I also have an unsupported SD/MMC card reader sitting on the mainboard). usbconfig -d 0.6 power_off Ends the interrupt spree. I'm running FreeBSD 11.0-STABLE #1 r316490 amd64. -- A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing on usenet and in e-mail?
