Here's another one:

fault virtual address =3D 0xc2
fault code =3D supervisor read, page not present
instruction pointer =3D 0x8:0xc047adcb

code segment =3D base 0x0, limit 0xfffff, type 0x1b
=3D DPL 0, pres 1, def32 1, gran 1
processor eflags =3D interrupt enabled, resume, IOPL =3D 0
current process =3D 36 (swi5: clock sio)
