9 watt-hours! Or 0.009 kilowatt-hours!

And if you want even more current bleeding edge updates, there is the "git" patches from kernel.org:

I like the work on making boots faster.

Look into the hdparm utility.  It allows control of the hard drive's lower level functions.

A tiny, cheap 9 volt NiMH battery into a simple 3 pin 7805 regulator's output right onto the sheeva's power supply ought to do the trick.  Have some resistor or something trickle charge the battery and it should be good to go.

"screen" is a nice way to log into a shell, detatch it, reattatch later, or connect to the same window multiple times from multiple locations.  Logging out won't kill the screens.

Its where I pull the 12 volt battery out of the UPS unit and extend the wires to a bigger battery.  7ah replaced with 70ah.  That's about it!

I have one of those cheap UPS supplies and have a automotive battery in a battery box next to it.  It will last for days...

Unfortunately, APC supplies float the battery voltage high, which requires the water level to be watched every month.  I believe APC does this on purpose, because it causes a battery that should last 15 years to only last 3 years.  Be careful with this setup, since the battery may be at line voltage and can shock or become a fire hazard.  That's why I keep it in a clean battery case.

What kernel version are you using?  I remember reading a lot of diffs between versions over storage on SD devices, on crude things like spinlocks and such.  It may be a bug that has been patched already.

Wish it has a SATA port, FP for image processing, and some IO pins for SPI devices to play with...  I can dream...

Anyone with physical access to just about any device can use JTAG to install a new bootloader or manipulate the chips at will.

Try copying a large file and see if the load average gets unreasonable.

You can always kill syslogd.  Might be something that keeps logging in a loop.

killall -9 syslogd
