Package: src:linux Version: 3.2.32-1 Severity: normal Dear Maintainer, The load of a realtime proces that I run is increased by more than 50%. With kernel 3.2.0-2 it was about 13% and since kernel 3.2.0-3 (and 3.2.0-4) it is around 19%. The only difference is the kernel that I boot so therefore I think it is related to the kernel.
