Seems there is a regression in the EC burst mode code:
EC burst mode does not solve the problem for this guy in current kernels any more.

I used one of the patches applied to:
http://bugzilla.kernel.org/show_bug.cgi?id=3851
(Sorry don't know the exact one any more, was about a month or a bit more ago).
With that one the buffered key issue was gone.

He now retested with current kernels: 2.6.13-rc6-git1-2 and the problem exists again.

Maybe Paolo should raise a new bug for that issue if not already done?
Please CC me.

Thanks,
