Good evening,
>> I'll try to track this commit. > > Thanks a lot!
I failed to find a working version today with CONFIG_PM=y (tested 3.2.6, 3.2.5, 3.2.0, 3.0.1, 2.6.32.8). I'll try older kernels tomorrow.
I'm very sceptical now : how can a bug with such a big impact (25% performance drop) can survive for so many years, with no one seeing it ? Good point is that benchmark can be easily done (it took less than an hour to test a new version). If you have patches to be tested, feel free to ask :)
In the meanwhile, do you think I can compile a working 3.7 kernel ? Maybe by activating / deactivating specific options ?
Olivier
