Hi everyone,I've tested the m5602-ov9650-2 branch again on my asus pw201 lcd display with an integrated cam.
It detects the cam, it works in livecam, xawtv, cheese.But, after starting and closing the applications 3 or 4 times, it crashes the machine (with a kernel oops I assume).
I haven't been able to capture the actual oops message, I can only include some messages about Bad memory state which occur just a moment before the kernel goes bananas and the machine reboots itself.
Have some of you done some stress testing of the driver? Are some of you using amd64 (or anything else than 32bit i386)? Thanks, Robert
