>Description:
If I boot my computer with my USB20 HD powered on, the system gives the next problem:

Fatal trap 12: page fault while in kernel
fault virtual address	= 0x21
fault code		= Supervisor read, page not present
instruction pointer	= 0x8:0xc044f50c
stack pointer		= 0x10:0xd57d7c58
frame pointer		= 0x10:0xd57d7c58
code segment		= base 0x0, limit 0xfffff, type 0x1b
			= DPL 0, pres 1, def32 1, gran 1
processor eflags	= interrupt enabled, resume, IOPL = 0
current process		= 36 (swi5: clock sio)
trap number		= 12
panic: page fault
Uptime: 14s

This only happens since I compiled my kernel with ehci support.
The HD size is 186GB, and it has two FAT32 partions (90Gb + 90Gb).
>How-To-Repeat:
Every time I boot my FBSD box with my external HD powered on.
