Hello! For some months now my X.org Xserver writes thousands of the same lines into the logfile /var/log/Xorg.0.log:
---------------------------------- [166447.122] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.138] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.155] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.172] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.188] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.205] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.222] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.238] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.255] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.272] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.288] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.305] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.322] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.338] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.356] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.373] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.389] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.406] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.422] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.439] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.455] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.471] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.489] (WW) AMDGPU(0): get vblank counter failed: Invalid argument [166447.505] (WW) AMDGPU(0): get vblank counter failed: Invalid argument ---------------------------------- This entry is repeated about 50 time per second and my current logfile grew to about 250 MB in the last 36 hours. At first this only happend when the monitors have been switched off, but now those line are also written, just when the screen lock is activated. I ran /usr/share/bug/xserver-xorg-video-amdgpu/script which created a 241 MB large file I didn't want to add here. :) The first "get vblank counter failed:" entries start around line 800 (61kb) which I could provide if wanted. I don't know if this is the right place for this or if this is an upstream problem. And how to supply the right information about the problem if I had to create a bug report. I found https://lists.debian.org/debian-x/2011/03/msg00099.html but the mentioned patch to quell everything after 5 messages seems not to work in my case. What can I do to get rid of those messages. Since it's not possible to rotate the logfile var/log/Xorg.0.log without restarting the Xserver the logfile grows over time until the filesystem is full. BTW: Before the system was rebooted yesterday the Xorg(?) process hat accumulated 29 GB RES-RAM according to top. This is a testing system: /etc/X11/X does not exist. /etc/X11/X is not a symlink. /etc/X11/X is not executable.
