Again, I had to hardware reboot because of another hang on "Stopping the
HAL daemon:". From today's kernel oops:
Jul 6 10:54:29 character kernel: (prefix of subsequent lines)
Unable to handle kernel NULL pointer dereference at virtual address 0000001a
printing eip:
c01bf732
*pde = 00000000

The "Call Trace" and "Code" sections look remarkably similar to those from
my previous kernel oops, as do all the lines up to the contents of the
e[abcd]x registers. In fact, they look just like the ones reported from
scyther.mit.edu and dodecahedron.mit.edu when they had kernel oopses.
