They happen on a RPi B and RPi B+ as well. I have tried different the SD-Cards on the B and the B+ of course. So I think it is not related to SD-card, manufacturer or RPi board. Usually they happen in the middle of the night when syslogd(8) tries to write something. I have never seen them happen when the RPi has some work to do, e.g. is compiling a port. Continuing out of the debugger prints the usual messages, but on reboot the RPi freeze. Only a power cycle will get it back to operating. Very often after such a panic happened my RPi gets "unstable" and panics within the next 48 hours again with the same cause. I found out that, if that happened and I force an fsck ignoring the journal there will be some minor issue fixed and the RPi is stable again. For the next 2 or 3 months. Ralf
