Package: linux-image-amd64
Version: 4.9+78
The current (backported) version of linux-image-amd64 (for Jessie) appears to need a few important fixes from the kernel source (upstream).
It appears that this has been fixed in the 4.9 series after 4.9.5 (per the bugzilla link above) - so can the package be suitably updated to incorporate this fix?
