modprobe: FATAL: Error inserting hw_random


i compiled an lfs system. it works properly but at bott time shows the foll mesg.
Code:
Loading modules for system devices
hw_random : RNG not detected
modprobe : FATAL : Error inserting hw_random (/lb/modules/2.6.12/kernel/drivers/char/hw_random.ko) : No such device
cant load module hw_random
missing kernel or username driver hw_random
how FATAL is it really??? i remember during kernel compilation, it had presented me an option to choose a random number generator (or something like that..) and i chose this.
how do i solve this?

It's not fatal at all. I mean, it's fatal to the module, but nothing else. And it's probably fatal because you don't HAVE a hardware RNG.

Linux will instead use its internal pseudo random number generator, so you will be fine.

You can see if your machine supports RNG. Although hw_random failures that appear in the syslog are a good indication that your chipset does not support RNG, there are other ways of determining for certain whether this applies to your machine.

How do I know if my machine supports RNG?

Nothing to be worried about if you see "hw_random" FATAL errors in your syslog (at startup). Just means your system does not support the feature (INTEL disabled RNG in most of their newer chipsets).

Hope this helps!

I wish I had a nice HW RNG.
