Thanks, these are all interesting (even if some of them seem to be
from random kernels).

Fengguang, is this a new script that you started running? Because I'm
*hoping* it's not that rc6 suddenly seems so flaky, and it's really
that you now have a nice new script that started reporting these
things better, even though many of them may be old?

Yes they are mostly not new issues to rc6. Just that I happen to start
this form of summary reporting now.

It's a bit late for rc6 and sorry about that! Next time when reporting
from rc1, we'll have much more time for working out proper fixes and
testing them out thoroughly.

Regards,
Fengguang
