USomIQ SOM can have 128GB of SLC NAND flash, but it will be rather expensive
due to high price of such NAND chips. However, with SLC you will not care about
data lost because Micron SLC NAND stands for more than 100k of write cycles
into a single cell

Could this possibly be related to how clean provided AC mains is ? I'm
just curious, as we've never had any of these problems, but we're also
completely off grid. Also for the record our power here is very stable and
clean. No blips, spikes, or any abnormalities one might see being connected

Anyway my last comment was a bit of a stretch. Seeing as this only effects
some boards, and not all. However it does strike me as odd that both of you
are having issues with the same kernel I'm running _right_now_. When it is
running rock solid so far for me.
Which leads me to believe that
What does cpufreq-set -g performance do?
Sounds like it would lock the BBB at max CPU clock speed, or at least, not
let it go down to the lowest speeds.
I found the generic Debian docs on *cpufreq-set*, but not the BBB specific
instruction set and meanings.

Hi all!
I'm working for a wind turbine manufacturer, and I want to set up a
super-robust data acquisition system. Basically it needs to:
- receive about 200 channels, single precision, 10-50 Hz through wired
network
- store data for some time (I need about 128 GB storage ideally)
- process it
OK.
I took my Rev.C unit (1c:ba:8c:d9:5e:dd) and loaded
bone-debian-8.1-lxqt-4gb-armhf-2015-07-05-4gb.img onto a
16 GB uSD card. Unit, power supply and card are trusted.
Absolutely no changes to the image, just install, boot, run. No updates,
additions or modifications.
No cape, only connections
lemme guess you are connected to your bone with USB and you dont have
internet connection sharing enabled ?

I am still having issues with the system. I have tried the fix listed by
Sean S but that did not fix it unfortunately. Does anyone know a command or
kernel update to force the colors to correctly render?

Correct...
I found the generic Debian docs on cpufreq-set, but
Are you using an Ethernet switch or crossover cable?
Some devices are not sensitive to the cable style and will automatically
switch TX/RX - possibly your PC. Without this function you'd need to use
either an Ethernet switch or a crossover cable.

Speaking of sealed case, and heating issues. Why not fill the area where
the BBB will sit with non conductive oil ? No idea if this is being done
professionally but it's been done with PC motherboards before . . .

Otto,
This will prove to be an interesting challenge for you.
To handle your environments, you will likely need to enclose whatever board
you choose in an IP67 or Nema 4 sealed enclosure. I don't think potting
or conformal coating will suffice if you have salt and/or potential for
condensing

I can't answer the question, however, are you aware of the industrial BBB
from Special Computing:
http://specialcomp.com/beaglebone/
Look at 22911. At least it covers your required temperature range.

Ok, so what I am wondering is: Why if this is kernel does the kernel work
fine for me. When using a Wheezy 7.8 rootfs ? It is fairly safe to say that
