I am attempting to do the same with with ts11 and have run into the
same issue.
I have managed to get a couple of camera grabs using spca5xx with
ts11 but the image is partially corrupt and I often run into the same
kernel panic as you.
I was wondering if you had made any more progress since this post ?
