Hi,

I have been succesfully using perf on MPC8xx, but on MPC83xx I get

Any idea of what the problem can be ?

Hello Segei, Florian and David,
I have an hardware with two ethernet interfaces, and with the two PHYs
inside the same component INTEL LXT973 which has only one interrupt.
I also have another hardware with two ethernet interfaces and two
independant PHYs. But the two PHYs are wired to the same

Scott,
The patch "Convert some mftb/mftbu into mfspr"
(beb2dc0a7a84be003ce54e98b95d65cc66e6e536) breaks startup on MPC885.
The CPU traps (SoftwareEmulation trap) at sched_clock() when trying to
read TBU with mfspr.
Reverting the patch solves the issue.
What's the prefered way to fix this ?
