Filed from caserun https://tcms.engineering.redhat.com/run/100139/#caserun_3856449 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 1. Boot up Actual results: rhgb does not come up Also, after login an error message appears if NOT using a 1080p monitor: """ Could not apply the stored configuration for monitors none of the selected modes were compatible with the possible modes: Trying modes for CRTC 380 CRTC 380: trying mode 1280x1024@0Hz with output at 1920x1080@0Hz (pass 0) CRTC 380: trying mode 1280x960@0Hz with output at 1920x1080@0Hz (pass 0) CRTC 380: trying mode 1152x864@0Hz with output at 1920x1080@0Hz (pass 0) CRTC 380: trying mode 1024x768@0Hz with output at 1920x1080@0Hz (pass 0) CRTC 380: trying mode 800x600@0Hz with output at 1920x1080@0Hz (pass 0) CRTC 380: trying mode 640x480@0Hz with output at 1920x1080@0Hz (pass 0) CRTC 380: trying mode 720x400@0Hz with output at 1920x1080@0Hz (pass 0) CRTC 380: trying mode 1280x1024@0Hz with output at 1920x1080@0Hz (pass 1) CRTC 380: trying mode 1280x960@0Hz with output at 1920x1080@0Hz (pass 1) CRTC 380: trying mode 1152x864@0Hz with output at 1920x1080@0Hz (pass 1) CRTC 380: trying mode 1024x768@0Hz with output at 1920x1080@0Hz (pass 1) CRTC 380: trying mode 800x600@0Hz with output at 1920x1080@0Hz (pass 1) CRTC 380: trying mode 640x480@0Hz with output at 1920x1080@0Hz (pass 1) CRTC 380: trying mode 720x400@0Hz with output at 1920x1080@0Hz (pass 1) """ Expected results: Make sure the whole booting process is correct and smooth, without any graphic fragments nor unaligned text/logos. There should be circle progress bar in the middle of the display.
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
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] RHGB works, no more errors.
