I'm using default shaders and I'm getting a bunch of these errors in the EngineLog.
Code:
Shader resource 'shaders/model.shader': ShaderLog: [Linking]

Fragment shader(s) linked, vertex shader(s) linked.
ERROR: error(#277) Symbol 'pos' usage doesn't match between two stages
ERROR: error(#277) Symbol 'vsPos' usage doesn't match between two stages
ERROR: error(#277) Symbol 'pos' usage doesn't match between two stages
ERROR: error(#277) Symbol 'vsPos' usage doesn't match between two stages

Should they considered as important errors ?

Those usually imply that you have declared the same name as an attribute in the vertex shader, and a uniform in the fragment shader. Double-check your names, and make sure there are *no* overlaps.

Yep, vsPos is defined in both VS_GENERAL and FS_LIGHTING at model.shader. Here is the EngineLog generated after running the Knight sample in the official beta4 SDK : http://pastebin.com/m67280971

*BUMP* Just wanted to note this problem occurs with original shaders and I didn't touched anything.

Does the shader work correctly?

The error seems to come from the fact that the varyings pos and vsPos are written in the shared vertex shader VS_GENERAL but not declared/read in all the fragment shaders.

Yes, everything goes well and there is no problem regards to the rendering in the knight and chicago samples. Just noticed at those errors in the engine log.
