Title:
Kernel 4.4.0-64 fails to provide /dev/dri/card0 for Radeon card
Status in linux package in Ubuntu:
Incomplete
Bug description:
After upgrading from 4.4.0-63 to 4.4.0-64, X.org will no longer load
my Radeon card and I am presented with a low-res fallback desktop.
Reverting to the 4.4.0-63 kernel restores ability of X.org to load the
Radeon driver.
I receive the following message in Xorg.0.log:
[ 36.346] (EE) open /dev/dri/card0: No such file or directory
lspci shows this card installed:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] Cedar [Radeon HD 5000/6000/7350/8350 Series]
