dmesg after one normal bootup

My video card is HD6850, motherboard is ASUS P8Z68-LE.

System can not boot up with radeon module very often. After powerup, the screen always goes blank, no any information, and it will not reboot immediately after pressing the reset button ( Reboot  occurs  10 or 15s later). System will boot up after pressing the reset button 2, 3, or even 7 times. And the whole system crashes very often after boot up normally, too. 
The system log has no any failure information after several  boot failures.
Version 3.13~3.15 or earlier versions have the same problem.
Any idea about it? 

P. S. Windows works very well.
