I was able to reproduce it with the .config you attached, and running it in kvm. It is caused by: "modprobe cryptomgr" called from swapper[1] This modprobe process does try to log an error, accesses /dev/console, which is not initialized in the kernel at that time, and the kernel module loader tries the load a module to support dev_t 5:1, which again runs modprobe, and ... Setting CONFIG_CRYPTO_MANAGER=y makes it disapper. The patch I sent seems to fix it. The bug is handled here: http://bugzilla.kernel.org/show_bug.cgi?id=12153 Thanks, Kay -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
