Hi, I'm developing DM3730 with Android 2.3.4 DEV-KIT 2.1. I met a problem. I made a LCD driver which suspend calling omapdss_dpi_display_disable(dssdev),resume calling omapdss_dpi_display_enable(dssdev);

The situation is: 1.When it went to suspend,and I click the power button in few seconds(10~),it can resume normally. 2.However,When it went to suspend,and I click the power button after 30 Seconds. It occurred kernel panic with a null pointer exception and every time show the error for different location. 3.If I don't call omapdss_dpi_display_disable(dssdev) in suspend and omapdss_dpi_display_enable(dssdev) in resume. The system suspend and resume normally.

4.Due to I need fine tune for power saving,these function must be called

Does anyone can help us? Any patch or clues would be very helpful. Thanks all you patiently watching.
