Hello,
no clue about this? I noticed that the numbers with the hex-value can go
on forever.
with a fresh reboot and no X11, I can read this information:

Hi,
I traced down my WebGL problems to core OpenGL issues.
If I run glxgears I get bad results.
The display does not show rotating gears but either two images
vibrating between (strobo-effect like) or even just one frozen image.
Sometimes I get a crash, like this:
$ glxgears
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
i965: Failed to submit batchbuffer: Input/output error
This is on a laptop with integrated Iron Lake graphics running
NetBSD/amd64.
I just did check dmesg to type out the details here, but see it
flooded with this errors:

now, If I rerun glxgears, I get a segfault:
