I thought I had some issues with 2.6.5, but as joq and slinkp(was that
you?) suggested it turned out to be bad ram. I was having random
lockups. Since removing the bad stick I haven't had any problems and I
was doing a good bit of work over the weekend. I can echo Frank's
comment that it feels good, generally. I'll be updating to 2.6.6
tonight. I'm optimistic about 2.6.x overall. But, that's just my gut
feeling and opinion, not any sort of scientific measure.
