Re: 2.6.28-rc9: oprofile regression

i am experiencing an issue, similar to the one reported in
http://lkml.org/lkml/2008/10/30/319.
bisecting showed, that commit b99170288421c79f0c2efa8b33e26e65f4bb7fb8
(oprofile: Implement Intel architectural perfmon support) caused the
problem.
oddly, the newly introduced api is not used, since the model struct is
set during the ppro_init call ...
Tim,
I just tested rc9 on a system I have available and I could not
reproduce this.
cpu family : 6
model : 15
model name : Intel(R) Core(TM)2 CPU 6300 @ 1.86GHz
stepping : 2
Does fix 7c64ade53a6f977d73f16243865c42ceae999aea work on your system?
7c64ade53a6f977d73f16243865c42ceae999aea has been included in rc9, but still
i experience this issue ...
the only difference to my cpu is the stepping (i have stepping 6) ... also, in
case it matters, i am running a 64bit kernel ...
tim
