Hi,

The linux kernel 4.4.34-v7+, version , used in 2017-01-11-raspbian-jessie-lite.img get stuck in boot.

[   31.572869] INFO: rcu_sched detected stalls on CPUs/tasks:

It happens in target-arm.for-upstream from Peter' repository and http://git.qemu-project.org/qemu.git/ branch master as well.

Hi,

One more information, the kernel get stuck in this line:

drivers/char/hw_random/bcm2835-rng.c:34 --> while ((__raw_readl(rng_base + RNG_STATUS) >> 24) == 0) {

Best regards,
