Gilles,

another issue (likely related, and that may help to diagnose) that I can 
see is that time is completely wrong;

For instance:


[root@buildroot ~]# time sleep 10

real	0m10.009s
user	0m0.002s
sys	0m0.013s

The system says that it spent 10 secs but I actually measured 25 secs.

Notice that I have CONFIG_HZ=1000

Time is correct when CONFIG_IPIPE is set to NO

Regards
Thierry
