Filed from caserun https://tcms.engineering.redhat.com/run/100139/#caserun_3856451 Version-Release number of selected component (if applicable): Build : RHEL-7.0-20131111.1 xorg-x11-server-Xorg-1.14.99.901-5.20131101.el7.x86_64 xorg-x11-drv-ati-7.2.0-6.20131023gitf1dc677.el7.x86_64 kernel-3.10.0-48.el7.x86_64 Steps to Reproduce: Make sure that your graphics driver supports KMS. Make sure you have rhgb quiet options in kernel commandline and no nomodeset option Log in 1. Logout Actual results: There are graphic fragments and so on for a second. Everything stays functional - probably not the biggest concern with this card. Expected results: There shouldn't be any graphic fragments or so on. In the end, the login dialog should appear.
Bug also affects AMD/ATI Kaveri [1002:1304]
You need linux-firmware >= 20131106-0.1.git7d0c7a8
This need to be retested but here i can not reproduce with : linux-firmware-20140102-0.2.git52d77db.el7.noarch kernel-3.10.0-89 mesa-dri-drivers-9.2.5 xorg-x11-drv-ati-7.2.0-8.20140113git3213df1 xorg-x11-glamor-0.5.1-4.20140115gitfb4d046c Note that bonaire GPU are still likely to lockup you will have something like : radeon 0000:01:00.0: GPU lockup In the kernel log. When GPU lockup screen is likely to go black.
We believe this is already fixed but moving to 7.1
This should already work in 7.0 but reassigning to kernel as if it is an issue than it is a kernel issue.
Retested on build : RHEL-7.1-20141006.1 linux-firmware-20140911-0.1.git365e80c.el7.noarch kernel-3.10.0-175.el7.x86_64 mesa-dri-drivers-10.2.7-3.20140910.el7.x86_64 xorg-x11-drv-ati-7.4.0-1.20140918git56c7fb8.el7.x86_64 xorg-x11-glamor-0.6.0-2.20140918git347ef4f.el7.x86_64 No longer affects: Radeon HD 8770 [1002:6650] No more fragments - logs out cleanly.
