Description

The boot message I see (on a fully installed server) is as follows:

WARNING: No randomness provider enabled for /dev/random. Use cryptoadm(1M) to enable a provider.

I have two systems that have the same illumos based OS install oi_148b (respin). The slow system is an Athlon X2. The faster system is a Supermico X9SCA-F with a E3-1280, where the OS is installed onto mirrored OCZ Vertex 3 SSD's this is a very fast box (a spec.org CPU 2006 result of 49.3 very close to topping the list). I only see this message on the "faster" system

Refer to:
https://defect.opensolaris.org/bz/show_bug.cgi?id=13547
and more interestingly
https://defect.opensolaris.org/bz/show_bug.cgi?id=38
The later states - "this is likely due to a race between KCF"

Note /dev/random is working just fine after the boot
