wow.

I've seen garbled top displays before, like the RES going -ve or things 
like that. But never anything like this. I am reminded of the scene in 
Poltergeist, where the couple get a paranormal expert into the house to 
take a look, and he natters on about how he saw a toy car roll across a 
room over the space of six hours... and then they open the door...

It looks to me like your structs are out of whack, and so when top comes 
along to read an element of a struct, it's using the wrong offset from 
base, and hence printf (or whatever) renders garbage. I.e., as if 
different headers are used in compiling the kernel and the rest.

Does ps give reasonable output? Are you sure you really cleaned out 
/usr/src before recompiling? Has the compiler been upgraded recently?
