Mark E. Amos was convicted pursuant to his guilty plea of possession with intent to distribute marijuana and conspiracy to possess cocaine with intent to distribute, in violation of 21 U.S.C. §§ 841(a)(1), 846. He appeals the district court’s dismissal of his 28 U.S.C. § 2255 motion to vacate his sentence as being time-barred. The district court granted a certificate of appealability as to this issue. Notwithstanding his assertions to the contrary, United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), is not retroactively applicable to his motion. See United States v. Gentry, 432 F.3d 600, 604-05 (5th *227 Cir. 2005). Accordingly, the judgment of the district court is AFFIRMED.
