v4.15: camera problems on n900
Hi!
In v4.14, back camera on N900 works. On v4.15-rc1.. it works for few seconds, but then I get repeated oopses.
On v4.15-rc0.5 (commit ed30b147e1f6e396e70a52dbb6c7d66befedd786), camera does not start.
Any ideas what might be wrong there?

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,
Pavel

Haven't seen the oopses yet; maybe they are only on linux-next? Anyway, bisect so far:

Hi!
In v4.14, back camera on N900 works. On v4.15-rc1.. it works for few seconds, but then I get repeated oopses.
On v4.15-rc0.5 (commit
ed30b147e1f6e396e70a52dbb6c7d66befedd786), camera does not start.

Any ideas what might be wrong there?
What kind of oopses do you get?
Hmm. bisect pointed to commit that can't be responsible.... Ideas welcome.
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?

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.
