In this latest case, I was working with the camera in kernel 2.6.27-8, I then upgrade to 2.6.27-10 and rebooted. After booting the camera was dead, it didn't even start. Like I said in the previous post, unplugging didn't work, I had to rmmod and modprobe to get it to work. I actually rmmod / modprobe with the camera unplugged, don't know if it makes a difference. I haven't tried booting with different kernels, but I think that could be a good debug test, just to make sure this is caused the upgrade process and not by changing kernels with the camera connected.
