I know the error message says I can try using the "no_fwh_detect" option.
So, I am not asking how to fix this error. I am asking what it means,
and what the difference is if the module would load with the firmware
space not locked read only, versus it loading locked but with the
no_fwh_detect option, versus just letting the intel-rng module not
load at all.
==========
[ 9.611318] intel_rng: Firmware space is locked read-only. If you can't or
intel_rng: don't want to disable this in firmware setup, and if
intel_rng: you are certain that your system has a functional
intel_rng: RNG, try using the 'no_fwh_detect' option.
==========
If needed, entire dmesg is here: http://pastebin.ca/3159151
The intel-rng module isn't loaded. The above error repeats in dmesg
if running modprobe intel-rng.
I'm on a HP xw8400, most recent BIOS (02.38.) There's no BIOS option
to unlock the firmware space
Question 1 - Am I correct, that without this module, the quality of my
random numbers is worse? (Appears this module uses quantum thermal
noise.)
Question 2 - What's the difference whether I do nothing and allow the
error to persist (or blacklist the module) -- or if I use the
no_fwh_detect option? Would using this option still get me the
quantum thermal noise effects on random numbers?
Basically trying to decide whether I should ignore the error or use
the option, and can't find anything saying what the drawback to having
to use the option is.
