I try to use hwpmc to find a net/lagg performance problem on a DELL
poweredge 2950 with dual E5440 (AMD64 7.1-PRERELEASE form yesterday) ,
but it seems that those processor are not recognized by hwpmc .
Is there a known fix / work arround ?

I also try to build an high resolution profiling kernel (config -p -p),
but it freeze at boot time.  A standard profiling kernel (config -p)
boots fine.

Any advice ?
