Kernel 4.4 does not panic but shows the following message when `ls -al`:

Kernel is still affected but behaviour a bit different - kernel crashed
immediately after mount

2016-06-07 Thread Joseph Salisbury 
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.7-rc1 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

apport information

** Tags added: apport-collected

** Description changed:

  Kernel panic happens after mount and ls specific btrfs image
  
  Way to reproduce:
  1. download and unpack btrfs image from tar(sparse file)(tar -Sxf img.tar)
  2. mount btrfs (sudo mount -t btrfs -o rw,noatime,compress=no,commit=5 
71bb49cf-26f1-484a-832c-e966f43adca9.img broken)
  3. list files in mount point (ls -al broken)
  
  the system down to kernel panic with log above
  
  (looks like 3.19.x and 4.2.x not affected, only 4.4.x)
