Well I did exactly what I'd done 3 months ago and found a faulty RAM chip this time
My guess is that back then the chip was still functioning some of the time, and happened to be fine just when I was doing the tests.

If you were running software RAID1 on that box, don't trust anything on the drives now. Maybe even if you weren't, but it is especially weird when alternate reads randomly revive bad data that you thought had been fixed already.
