I'd guess the best approach is to add trace messages or to actually trace execution (as far as possible for a kernel driver that affect the frame buf= fer) in order to identify the exact point of failure. But as I said, I have no idea where to start ... --=20 You are receiving this mail because: You are the assignee for the bug.=
