I'm using this source tree since I'd like to have KMS https://github.com/ FreeBSDDesktop/freebsd-base-graphics Anyway. systat reports 2/3 of the interrupts being fired by XHCI (around 1600+) even though there is no device plugged in. (I've compiled a custom kernel where the driver is not compiled into the kernel so at least this is not a permanent issue for me). I'm not quite sure how to provide more information on the issue and how to proceed here so pointers would be highly appreciated. Kind regards, raichoo
