Bug#865220: linux-image-4.9.0-3-amd64: unable to handle kernel NULL pointer dereference: in6_dev_finish_destroy
Package: src:linux
Version: 4.9.30-2
Severity: important
Dear Maintainer,
The problem outlined in the kernel log capture seems to occur some time after
heavy use of Docker containers. I have not been able to reproduce this problem
on linux-image-4.9.0-2-amd64 (Kernel version 4.9.18-1), but the problem is
difficult for me to reproduce.
-- Package-specific info:
** Version:
