For the time being, just an observation: I monitor various parameters on my systems, and among them is "Committed memory", the Committed_AS value in /proc/meminfo. Since upgrading to the 6.5.x series, I noticed the value there grows way higher values then previously in hppa, even if the machine is idle. Values seem to rise up to around 1.6 Gbyte, long-term average is rather 200-300 Mbyte. Also, I cannot see any memory hogs in top. The workload hasn't changed in months. To sum it up, I reckon something went wrong in the memory usage accounting. Is this already on radar, or should I start bisecting? That might take a lot of time, though.
I doubt there is a specific memory leak in the parisc code. Usually we just touch driver code or other arch-related code, so if there is something wrong, then it must be in generic code and should be visible on other platforms too. We changed to the SLUB allocator, but I don't think this makes any difference either. Helge
