What happens if we leave the HP filter un-reset with threshold?

You're right the comment about reset HPF made it look like they're related. But that one too is only needed if there's a threshold wakeup. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkmIFbEACgkQOjLpvpq7dMpaGACdFxp4M/7TyHf8vCLfbNecglSm hrYAnR+lW9hZW+X37F10hvvkRjIrmii2 =PFNA -----END PGP SIGNATURE-----
