I think I found my issue. I have a Dell T5610 and a Dell T5600. The T5610 will install Harvester, but it doesn’t work right… very strange behavior that I think might have something to do with Dell’s firmware. The T5600 works fine… I think, still testing.
I wondered if there was an issue with older processors, but that doesn’t seem to be the case; as both systems have the same Sandybridge Xeon with the only difference between the two being their mobo and firmware.
