What is the date of you kernel sources? (I mean on the installed kernel, not the new one). There was a problem earlier this year (between 5.0 and 5.1) that generated sig 4s and 11s. I was sure that I had a hardware problem, but saw some odd behavior in other places that made me suspicious. I built new kernel for this system on another system (copied over my config file and my make.conf) and loaded and booted that. Suddenly I could make buildworld again! FWIW, my T30 is currently showing hw.acpi.thermal.tz0.temperature of 79 C. It is in the middle of a buildworld. Before I started it was sitting at about 41 C. This seem no not cause any problems, although it is pretty warm. It seems stable and is not going higher. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
