They seemed to be in unrelated processes -> not useful for
debugging. I tried again, but this time it hangs, similar way to
-rc0.5. (That might be good news).
Does it work for you on N9?
Thanks,

Haven't seen the oopses yet; maybe they are only on linux-next?

Hi Pavel,
I tested N9 and capture appears to be working from the CSI-2 receiver
(media tree master, i.e. v4.15-rc3 now).
Which pipeline did you use?

I'm using the "main" sensor (5MPx) and am using capture (not preview)
pipeline.
I tested linux-next in the meantime, and that one seems to
work. (Which is strange, I believe it oopsed before. Perhaps something
random?) With linux-next working, it should not be hardto figure out
what is going on.
Thanks,
Pavel

I tested next-20180219 and camera does not work there. It leads to
nasty oops. I tried to capture the oops with dmesg > file, and that
one oopsed, too. usb networking also has problems... fun.
Camera works ok in V4.16-rc1, but if I use the camera, next shutdown
will oops. I'll try to collect more data there, too.
