Xorg freezes on second start

[Владимир Новосельцев]

Hi,
I'm having the following problem:
After recent xorg update, xorg-server started to freeze on second start, 
i.e. if X server started from console second time it completely freezes 
system.
I've tried either radeon and radeonhd drivers, radeon from ports and 
from git, radeonhd from git. Then X started for the first time, I can 
switch to console and back with out problems. On second start it locks 
some where after mode-setting.

System: FreeBSD/amd64 7.1p2, Gigabyte P35-S3 MB, CPU C2D E6550, RAM 6Gb, 
ATI Radeon HD3870 512Mb.

WBR,
