Zimablade starts up with clean error -22

My Zimablade seems to be trying to do a clean of its file system. GRUB appears, I select Ubuntu then the Ubu logo appears and after awhile I get a text mode screen with error -22. Is there any way to get past this?

More detail: the error is EDAC pnd2: Failed to register device with error -22

Some say this is due to not having ECC DRAM but it ran just fine for months prior.

Do you have other DDR? Maybe we can try to replace it to confirm the problem.
