Hi,

With the most current git kernel (90a4c0f51e8e44111a926be6f4c87af3938a79c3)
I'm still getting the same reproducible kernel panic when trying to read a
particular file stored on a btrfs filesystem (as seen in the log there are
indeed disk media errors on this disk).
I'd like the "software" part of this to be fixed - btrfs should definitely
not oops even in case of media error - before sending the disk to RMA. Is
there anything I can do to make progress on this ?

Is this kernel compiled with "Compile the kernel with debug info" (in
the "Kernel hacking  --->" configuration section)?

It would be nice to have the specific line of code passing the NULL pointer.
