Bug#638555: linux-image-2.6.32-5-amd64: CPU time overflows for long-running processes.

Package: linux-2.6 Version: 2.6.32-35 Severity: normal When a process exceeds 2^31-1 (probably) milliseconds of CPU, the CPU time counter becomes corrupt. I have noted the following effects: 1) The process disappears altogether from top (although the overall usage stats show it to be running)
