White Screen on mini6410 with P43 display

Hi, I have some problems with the new P43 (rev. 1510) displays on my
mini6410 board. The displays do not always start correctly. Sometimes
(every 10 to 20 boots) screen gets completely white for the next turn off
and on. In the other cases, everything is ok. I tested this modules (20
different) on Linux (2.6.38 kernel) and Windows CE. P43 (rev. 1503) and H43
working properly.

Someone had a similar problem? 
Thanks.

Hi,
I have the same problem on Windows CE with P45 rev. 1510.
On Linux it works OK.
Does anyone have a solution?
