While the first good commit isn't applied downstream (in order to fix previous kernel versions), I currently recommend using stable kernel 4.7.4, available at http://kernel.ubuntu.com/~kernel- ppa/mainline/v4.7.4/
There are newer stable kernel versions available, but I haven't tested them. I can confirm, though, that kernel 4.7.4 solves the "freezing" issue. One running 64-bit Ubuntu Linux and interested in installing kernel 4.7.4 must download these files: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.4/linux- headers-4.7.4-040704_4.7.4-040704.201609150330_all.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.4/linux- headers-4.7.4-040704-generic_4.7.4-040704.201609150330_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.4/linux- image-4.7.4-040704-generic_4.7.4-040704.201609150330_amd64.deb ...then open a shell terminal window, "cd" into the folder where these 3 DEB packages were downloaded to, and then run the command "sudo dpkg -i linux-*.deb" (without the quotation marks) in order to manually install the three DEBs. Then reboot the system. For a complete list of kernels, visit http://kernel.ubuntu.com/~kernel- ppa/mainline/?C=N;O=D PS: for 32-bit systems, the 3 DEBs to be downloaded and installed are: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.4/linux- headers-4.7.4-040704_4.7.4-040704.201609150330_all.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.4/linux- headers-4.7.4-040704-generic_4.7.4-040704.201609150330_i386.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.4/linux- image-4.7.4-040704-generic_4.7.4-040704.201609150330_i386.deb If your system is hanging/freezing to the point that you can't even login into the GUI, power off your computer, then turn it on again and press the Esc key until you get into the GRUB menu. Afterwards, press the E key in order to edit the grub menu, then go to the first instance of the code "$vt_handoff" and add the "nomodeset" parameter right before it. Example: => Before = quiet splash $vt_handoff => After = quiet splash nomodeset $vt_handoff After adding the "nomodeset" parameter, press the F10 key (or the Ctrl X key combo). Linux will boot with Kernel Mode Setting (KMS) disabled, then you will be able to log into the Graphical User Interface (GUI) and then download and install a stable kernel. Sorry for the long comment that is not a relevant info for those investigating the bug. It just so other users know how to "deal" with the bug while it's not fixed/removed from previous kernel versions. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-amdgpu in Ubuntu. https://bugs.launchpad.net/bugs/1608042 Title: 64-bit XUbuntu 16.04 "Xenial" hybrid graphics (Intel + AMD): AMDGPU crashes / freezes / hangs entire system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1608042/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
