Bug Description
One of our Ubuntu Core 16 devices failed to boot after a refresh recently [0]. After some debugging it turns out that it hangs in early boot because there is not enough entropy available. Snapd is using entropy to init it's CRNG and a change in snapd broke the boot. However while debugging/fixing this issue I was wondering if it would be possible to backport the new jitter entropy patches from kernel 5.4 [1] to the older LTS kernels.
Thanks,
Michael
