Display artifacts going to suspend

Hello, I am investigating a strange behavior on iMX53 while going to suspend. Sometimes (rare) during switching to suspend display shows splash screens of red, then green, then blue, then chess board and then reset. Looks like oops or panic, but no panic dump is generated. I am pretty confident that we don't have any such functionality implemented in our software. For me it looks like something bad occurs in IPU and it tries to signal about that with these splash screens.

Does that make any sense to anybody? I am quite stuck with this and any clue would be very appreciated.


Thanks, Ivan
