After running fine with zero issues forever, I'm now getting a ZOMBIE status in cgminer with the following error displayed in the console:

ERR: Asked to memcpy 0 bytes from usbutils.c _usb_read(): 3075
HFA: OP_USB_INIT failed! Operation status 20 (Regulator programming error)

I've tried cycling power, restarting, doesnt seem to help.

Any ideas?  Huh

Any time I've seen that error it was a loose or disco'd power connector or the PSU wasn't turned on.  Have you tried a different supply?

I did, tried another supply that is guaranteed working, and got the same error.
Did you unplug the USB cable when you changed power supplies?

I don't think so, I powered down PSU 1, swapped PCI connectors to PSU 2, and powered up PSU 2. At what point should I unplug USB and plug it back in?
While the 12V power is off. Because the board can be powered over USB (at least the microcontroller), it never really fully power cycles if you just remove the 12V.

I've completely powered down the board (both 12V and USB unplugged). Then I plugged in USB first, then 12V. I still the the same repeating reset cycle with that error.
