Hm, you broke perf top:

PerfTop: 0 irqs/sec kernel:-nan% exact: -nan% [1000Hz cycles], (all, 16 CPUs)
-------------------------------------------------------------------------------------------------------

samples pcnt DSO
_______ _____

Can't parse sample, err = -14
Can't parse sample, err = -14
Can't parse sample, err = -14
Can't parse sample, err = -14
Can't parse sample, err = -14
Can't parse sample, err = -14

and perf record+report as well:

aldebaran:~/linux/linux> perf record -a sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.119 MB perf.data (~5201 samples) ]
aldebaran:~/linux/linux> perf report --stdio
The perf.data file has no samples!

so i'm unpulling these bits.

Thanks,

Ingo
