I'm using LMDE 2 (stable 3.16 kernel). I installed the 4.8 kernel from backports and it gave me warnings on postinst about possibly missing firmware for my radeon module. Then, I upgraded my system ENTIRELY from the backports thinking maybe that would fix the issue. But my PC would still not boot using the 4.8 kernel. Any suggestions?Thanks. I'm attaching the tee-d output from apt-get from when I first installed 4.8.Reading package lists...Building dependency tree...Reading state information...The following extra packages will be installed:  liblxc1 linux-base linux-image-4.8.0-0.bpo.2-amd64 python3-lxcSuggested packages:  linux-doc-4.8 debian-kernel-handbook btrfs-toolsRecommended packages:  bridge-utils debootstrap dirmngr libpam-cgfs lxcfsThe following NEW packages will be installed:  liblxc1 libvirt0 linux-image-4.8.0-0.bpo.2-amd64 python3-lxcThe following packages will be upgraded:  linux-base linux-image-amd64 lxc3 upgraded, 4 newly installed, 0 to remove and 160 not upgraded.Need to get 42.2 MB of archives.After this operation, 190 MB of additional disk space will be used.Do you want to continue?
