Hi After applying latest updates to Debian testing, my system here will not boot to graphical mode on kernel 4.8.0-1-686-pae and 4.8.0-2-686-pae. During boot it drop connection to monitor, and not even a command prompt is available.
Same setup work fine with kernel 4.7.0-1-686-pae. lspci show 01:00.0 VGA compatible controller: NVIDIA Corporation ION VGA (rev b1) And X will use xserver-xorg-video-nouveau for this. In syslog for failing 4.8.0-2 I see nouveau 0000:01:00.0: bus: MMIO write of 80150000 FAULT at 61a804 nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 61a804 nouveau 0000:01:00.0: bus: MMIO read of 00000010 FAULT at 640000 nouveau 0000:01:00.0: bus: MMIO read of 00000001 FAULT at 640000 nouveau 0000:01:00.0: bus: MMIO read of 00000010 FAULT at 640000 nouveau 0000:01:00.0: bus: MMIO write of 00000014 FAULT at 640000 I have then switched Debian over to default start in command prompt. "systemctl set-default multi-user.target" Still 4.8.0-2 end with no graphic output and dead monitor. Then I found that if I boot 4.8.0-2 with kernel parameter "nomodeset" it start, I then get a command prompt, I can also start graphic mode by startx, but not with the resolution of my monitor (PHILIPS 273V5HSB 1920 x 1080) more some generic standard 1280x720. So question is then if we have error in nouveau or in some modeset thing in kernel??? Until further I have to stay with 4.7.0-1 to use my system. Brgds Torben
