He didn't say.

I was on 2.6.39.2 when I purchased the motherboard, so can't personally
vouch for anything earlier. However other posters, who were on earlier
kernels, referred to the behaviour that I am now experiencing on 3.1.5 -
i.e. that the "nobody cared" fault occurs and the device then continues
to "work" but extremely slowly (from 2.6.39.2-3.1.4 it stops working
completely).
