Hi Everyone, Recently I upgraded a machine from 6.8 to 7.2 (Nitrogen). The machine is randomly frozen and nothing works afterwards. No ctrl+alt+f2,f3,f4 etc. The machine seems to be reponsive since I can ssh to it. I've attached the /var/log/Xorg.0.log file The kernel I am running is: 3.10.0-327.36.2.el7.x86_64 The output of lspci is as follow: .... 01:00.0 VGA compatible controller: NVIDIA Corporation GF116 [GeForce GTX 550 Ti] (rev a1) ... ... The output of lsmod | grep nouveau nouveau 1403757 2 mxm_wmi 13021 1 nouveau i2c_algo_bit 13413 1 nouveau drm_kms_helper 125056 1 nouveau ttm 93488 1 nouveau drm 349210 5 ttm,drm_kms_helper,nouveau i2c_core 40582 5 drm,i2c_i801,drm_kms_helper,i2c_algo_bit,nouveau video 24400 1 nouveau wmi 19070 2 mxm_wmi,nouveau rpm -qa *nouveau* xorg-x11-drv-nouveau-1.0.11-2.el7.x86_64 I am suspecting that the bug is triggered by the browser (firefox/chrome) but not sure though. Is there a solution / workaround to this? I've done some research on the net and saw the following links that describe the problem. https://bugzilla.redhat.com/show_bug.cgi?id=1158879 https://bugs.freedesktop.org/show_bug.cgi?id=87819 https://bbs.archlinux.org/viewtopic.php?id=188004 Best regards, -- Valentin Bajrami Kapteyn Astronomical Institute University of Groningen Postbus 800 NL-9700 AV Groningen The Netherlands Phone: +31-(0)50-3634068
