This is starting to sound similar to what btckess experienced.
Follow his troubleshooting step(s) up to resolution from here to see if any of it relates:

Not running on a pi (it is a desktop with 12GB of ram - with plenty available, so there is definitely not a shortage of ram).

The hub has nothing but the three miners in it (my usb fan died, so I am running a fan out of the mains at the moment). Would like to move a compaq (running on a different machine for months with absolutely no problems) onto the same hub, but I am not sure that is possible.

I just ordered a usb current measuring device (probably won't arrive for a couple of weeks, but I will see if I can learn any more then).

I do have one question about hardware errors and power (I have actually read this entire thread several times grasping at anything). I am getting maybe one hardware error (on each stick) every two hours (frequency doesn't seem to matter - about the same rate at 75 MHz as 150 MHz). Is that "good enough," or should I try to up the voltage?

I'll take a peek a Gentoo this weekend.
I use to enjoy using that, but have nearly forgotten it still existed these days.

Thanks. Let me know if you need me to compile cgminer with any flags to help debugging (not really an expert on that, but I should be able to follow simple directions).
