>Description:
I get two different kernel errors from the intel_sprite.c code. The first and most common is:
[ 148206.6236226] kern error: [drm:(/usr/src/sys/external/bsd/drm2/dist/drm/i915/intel_sprite.c:132)intel_pipe_update_start] *ERROR* Potential atomic update failure on pipe A: -35
The second one is:
[ 148794.5234694] kern error: [drm:(/usr/src/sys/external/bsd/drm2/dist/drm/i915/intel_sprite.c:205)intel_pipe_update_end] *ERROR* Atomic update failure on pipe A (start=874637 end=874638) time 2 us, min 763, max 767, scanline start 765, end 768
I've noticed in the source code that there are a number of:
#ifdef ___NetBSD___
statements. The first error, as you can see, happens at line 132, which is in one of those ifdefs.
>How-To-Repeat:
Open a browser like Firefox, Midori, or in my case Seamonkey. Open a couple of tabs and go to a few links. The errors show up in the xconsole.
