RE: rngd read errors at boot time
Reindl,
I would have to disagree with you. I get the exact issues in the bug report on a Sandy
Bridge machine without a HRNG (no rdrand extension).
A default install of Fedora 22 has the rngd service enabled and it actively searches for
/dev/hwrng.
This is obviously bad error handling and not a security issue.
