It has an NEC OHCI usb controller. When I plug any usb device in (i'm using a mouse for simple testing) the system locks up such that no console processes respond but i can still switch virtual consoles using the alt-Fn. I assume this means that interrupts/bottom half code is still working but that top level processes are no longer being scheduled?. Enabling all of the usb debug values in sysctl beforehand does not produce any output (nor does usbd -d -v -v produce any when i plug something in). Any suggestions? Is anyone else having usb ohci problems with 5.0? I'm recompiling the kernel with DDB as I write this. tia, Greg
