Description ken moffat 2018-03-30 01:32:39 UTC
I recently bought a low-end Ryzen and needed a basic video card with a vga connector, so I bought a GT710 (GK208B). The system is intended to be used for compiling/measuring builds from source, but it is almost unusable in X because of video errors which cause the desktop to lockup (no mouse clicks or keyboard, MagicSysRQ works).

Packages: linux-4.15.12, gcc-7.3.0, glibc-2.27, mesa-17.3.7, xorg-server-1.19.6, nouveau-1.0.15.

So far this bug has bitten me twice. The first time I had built xorg and was running fluxbox while I built the rest of my desktop. I had 4 or 5 urxvt terms open across two desktops, nothing else, running a compile in one. I had been reading mail on the second desktop, then tried to go back to the first to check progress.

After waiting a little I rebooted.  The system log had what I thought was a lot of output (about 50000 lines, I think), starting

(similar CHSW ERROR messages after that).

Because of the other problem, which I will post after this, I then tried using hte modesetting driver in Xorg. But I got a similar, bigger, report (left it trying to compile, came back to find an xscreensaver screen, when I rebooted I had almost 1.3 million lines in the log:

 (and then a few more before it rebooted).

Because this is a new machine, I have no idea if this is a regression or has always been like this.
