I recvsuped some hours ago and now I have the following (this time with DDB 
trace):

Fatal trap 12: page fault while in kernel mode
fault virtual address	= 0x24
fault code		= supervisor read, page not present
instruction  pointer	= 0x8:0xc0571d36
stack pointer		= 0x10:0xcdca4ca4
frame pointer		= 0x10:0xcdca4ca4
code segment		= base 0x0, limit 0xfffff, type 0x1b
			= DPL 0, pres 1, def32 1, gran 1
processor eflags	= resume, IOPL=0
current process		= 11 (idle)
