The last traces has systemd in there, but good old sysvinit crashed spectacular too. > FWIW, I am running: > * A rev2 Model B > * Firmware commit 9c3d7b6 "Add latest linaro gcc toolchain: > gcc-linaro-arm-linux-gnueabihf-raspbian-2012.08-20120724_linux" > * Upstream U-Boot (very recent) and kernel > * Using Ubuntu 13.10's packaged ARM cross-compiler Huh, switching compilers made a difference... I was using debian's cross compiler [0], 4.8.2, which has a couple of patches [1]. With my old self compiled and unpatched toolchains I didn't yet get any crashes, I tried: binutils 2.20 + gcc 4.4.4 binutils 2.21.1 + gcc 4.4.7 binutils 2.23.1 + gcc 4.7.1 binutils 2.24 + gcc 4.7.2 but with these versions (also unpatched) I do get the crashes: binutils 2.23.2 + gcc 4.8.1 binutils 2.24 + gcc 4.8.2 Which one are you using? gcc-arm-linux-gnueabi [2] or gcc-arm-linux-gnueabihf [3]? Maybe there's a reason the former is 4.7 while the latter is 4.8? In case you're using 4.7, care to give 4.8 a try? In any case, I'm hesitant to blame this on a compiler bug since booting any of those kernels with "nousb" didn't yet end is weird panics.
