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)
kernel: type 12 trap, code=0
