I copied the wrong line from mount, debugfs is always mounted on Ubuntu
none on /sys/kernel/debug type debugfs (rw)

Still, I don't have any output right after the crash, see above. Tried several times 1080i recordings, either
no error state collected


Below error is with a 720p recording, which behaves and looks different

Again with 1080i, I also noticed the stacktrace is not always the same, however ends always at the same point (intel_unpin_fb_obj):

Is /usr/share/apport/apport-gpu-error-intel.py of any help, where can I find it.
Is the kernel stack trace of any good ?  See also my previous post.
Other possibilities of getting a trace ?

I have quoting enabled in Outlook.
