Bug#1013982: linux-image-5.10.0-15-amd64: Available entropy is a constant

2022-06-28 Thread Alexander Kirillov
Package: src:linux
Version: 5.10.120-1
Severity: normal

Dear Maintainer,

In this particular version of the kernel available entropy counter is always 
256. At least on my box. The usual range is 2000 to 4000.
I've noticed because I have it graphed in munin.

# cat /proc/sys/kernel/random/entropy_avail
256
