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:
