dmesg output with bubble3d running ~16 hours (with one interruption)
Computer failed second-stage burn-in testing. Was able to run mprime with
blended tests overnight. Running the 3D screensaver (initially pinion) with
mprime doing "in place FFTs" (loads CPU, cache, little memory): caused X to
crash. Lightdm restarted it automatically, but I had no mouse pointer.
I then upgraded all of the relevant software to newer versions:
Package: xorg Version: 1:7.7+5
Package: xserver-xorg-video-nouveau Version: 1:1.0.10-1
Package: libdrm-nouveau2 Version: 2.4.50-1
Package: libgl1-mesa-dri Version: 9.2.2-1
Package: xscreensaver-gl Version: 5.23-1
uname -a
Linux torchlight 3.11-2-686-pae #1 SMP Debian 3.11.10-1 (2013-12-04) i686
GNU/Linux
Running bubble3d with mprime doing "in place FFTs", I get a soft lock-up within
about 30 minutes. I switched to bubble3d because the screen with the mouse
pointer was experiencing ~50% slow-downs even if the pointer was not drawn (it
gives info about the gear under the pointer). All the GL screen savers also
seem to suffer significant slow-downs with the option to display the frame-rate
enabled. On the order of 20->5 fps. This slowdown was not as evident prior to
the upgrade (so may be a regression).
When running bubble3d for about 16 hours, with the computer otherwise idle, I
logged two sets of Cache errors. However, without the soft lock-up. I plan to
test with an ATI card to see the problems may be related to power stability
rather than software. The motherboard is now about 10 years old, so the
capacitors may be drying out.
