Hi,

I do have a corrupted btrfs filesystem that immediately triggers a "BUG: unable to handle kernel NULL pointer dereference at 00000000000001f0" type Oops on mount. Full oops in https://www.spinics.net/lists/linux-btrfs/msg64592.html

While the file system contains kind of sensitive data,  I can give an btrfs-image for download in private e-mail. Would the output of btrfs-image -s be helpful as well?

I didn't try with a more recent kernel yet but will try with the current kernel as soon as someone gets in touch with me to investigate things further. I am aware that this issue won't be taken up in a matter of days, but I am willing to invest some time as soon as I know that things will go forward from here.

I intend to scrap the image by the end of 2017 if this issue isn't followed up, so feel free to close this in January 2018 without getting in touch again.

I am prepare to answer questions ;-)

Cheers
Marc
