Hello!
I work with DM368, dvsdk_4_02, linux-2.6.32, GStreamer (commit 1062 from trunk) and CMOS OmniVision OV2715.
I have small problem - on resolution 1920x1080 I can't capture video. Log from linux:

Why interrupt not work on 1920x1080 resolution? How can I debug and solve this?
Thank you and excuse me my bad english.
