This is probably completely wrong for this problem but in the tiny case it isn't, maybe it will give someone an idea: I remember in the old times (tm) that there was a trick by which the msgbuf is supposed to be preserved across soft reboots. I don't know the details, and it might just be valid for i386 but part of that deal could be that some code tries to parse that memory area for valid msgbuf and due to some garbage, fails with such a panic.
