I’m not sure if this is related, but I’m on debian jessie 8.1. I noticed that after I upgraded a few packages yesterday (apt-get upgrade) TrueRNG was broken. Unfortunately, I don’t remember which packages I upgraded.
Here are a few things I noticed:
- systemd complains about “invalid key/value pair” which I think is related to the file format of the rules file. It is ASCII text, with CRLF line terminators. I resaved it as just ASCII text and I’m crossing my fingers. It’s working now after a reboot, but the last time, it took a hour before it gave up/reset.systemd-udevd[17049]: invalid key/value pair in file /etc/udev/rules.d/99-TrueRNG.rules on line 7,starting at character 210 (‘\n’)
(I edited the file a little to try a few things, but the format was unchanged when systemd/udevd threw this error)
I was rebuilding/resizing a filesystem, which I assume is why the last day has been lower than usual. The points where it dropped to zero are where the rng daemon would not start and entropy was 0 or very low. It probably would be higher if I removed rng-tools so that the kernel would have relied on good old fashioned entropy collection.

I just received a new V2 today, and ran it through some of its paces. I am not getting that much variation in results. I am on linux and pulled 64M from /dev/ttyAMC1 (I have a V1.0 in /dev/ttyAMC0). I used ent to analyze the byte count.
