Never seen this one and I changed nothing in select and af_unix. can you
send me the output of objdump -d fs/select.o too so I can find exactly
which line of C code is oopsing? (make fs/select.lst and sending me
select.lst would be fine too)

Did it ever happened to you on older kernels or with different X server?
I guess the hardware, X or some driver is giving you problems, I doubt
the problem is really in the poll afunix path.
