I updated the system to r286833 and started to build the world in a loop. root@pizelot:/usr/src # cat loop_build.sh #!/bin/sh while true do make cleandir make -j4 kernel-toolchain make -j4 buildkernel make -j4 buildworld date >> loop_build.log done I've tested two kernels, a custom kernel with INVARIANTS disabled and the default RPI2 kernel. With both kernels I was not able to reproduce the initial problem. Nevertheless, both attempts end with a crash and reboot (after several loops). The custom kernel crash after one day, the default RPI2 kernel after 5 days and (6 rounds completed). I've no further data related to these crashes, I don't think that it has to do with with our problem. The used SD Card was a "Samsung SDHC 32 GB C10 UHS-1 MB-MGBGB". -asc
