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?

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? -- Regards, Sakari Ailus e-mail: sakari.ai...@iki.fi

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.
