In my F7 x86-64 ernel, I notice the same thing.  The reason may be that there
appears to be no dwarf data whatsoever for the function.  Did the default kernel
AFLAGS change recently?

IIRC, Roland's build-id patches include a piece that adds '-gdwarf' to all GAS
command lines.  That should cure this problem. http://lkml.org/lkml/2007/7/11/445

Another possible solution is to search the ELF symbol tables for probing targets.
This has come up before, in the context of debuginfo-less but otherwise normal
programs, but we haven't built this yet.  Perhaps we should transform this bug
report into that feature.
