The one worrying thing is that with 7.1 RELEASE this does not happen. So something, either in the kernel, or my configuration files, changed. I had a mergemaster issue that I thought was between 7.1 STABLE -> CURRENT but perhaps it happened the first time I updated from 7.1 RELEASE. I know this because I had problems with an unrelated part of the system (wireless) that a mergemaster run on CURRENT fixed. > Judging by "2000/Something" you have mentioned below, I suspect not. > Well, we'll know tomorrow. > > Just out of curiosity -- what are you using to visualize this?
