Because reduced test cases are cuddly, I have produced one (attached).
=)

I found I could produce the same failure with the ltp testsuite, so I
reduced that instead.

And the failure message again:
root at test148:~/foo# ./adjtimex02

I have updated the system map at
http://people.ubuntu.com/~jbailey/System.map-2.6.18-rc4-pa4
with the one for the kernel recompiled with gcc-3.4.6.

Tks,
