Description Aragon Gouveia 2008-05-15 00:50:01 UTC
If a USB device is inserted into my system after it has booted up, the kernel panics. 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 rx0, 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.
