USB devices that are inserted before bootup do not cause a panic. This ONLY occurs if usb is loaded via a kernel module (in my case from loader.conf). If I had devices ehci, uhci, and usb to my kernel config then the problem goes away. Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0x290 fault code = supervisor read data, page not present instruction pointer = 0x8:0xffffffff8061b1e5 stack pointer = 0x10:0xffffffffaad95dd0 frame pointer = 0x10:0xffffffffaad95e10 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 31 (usb3) trap number = 12 panic: page fault I have tried to get something that can be debugged, but when this crash occurs no dump gets written. The system completely hangs at this point and requires a hard reset. If I enable KDB/DDB in the kernel then the problem goes away! I am not sure how to debug this further - open to suggestions.
