modprobe: FATAL: Error inserting hw_random
 

i compiled an lfs system. it works properly but at bott time shows the foll mesg.
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?

is it
/lb/modules/

or

/lib/modules/

yeah..sorry. its /lib/modules..

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. :)

so does that mean i dont need random numer generator for my LFS install (since it is continuing to boot properly and also running without a hitch as of yet)?

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!

:jawa:

I wish I had a nice HW RNG. :)
