[adding linux-media mailing list & reattaching the kernel log file]


Can you get any more of the kernel log?
What kernel version is this?

There are 3 out-of-tree kernel modules loaded.
  lepton(O) ap1302_new(O) galcore(O)

Can you reproduce the problem without those modules being loaded?
If they are part of the problem, we probably can't help you.
