Thanks for the additional info. Judging the bug reports I found at freedesktop.org, I think we can safely confirm this bug. It seems the lost interrupts might have something to do with it actually.
Unfortunately, there doesn't seem to be much activity there. According to the comments at https://bugs.freedesktop.org/show_bug.cgi?id=7456 this seems to be a well-known problem. Unfortunately, the comments also claim nobody's actively maintaining the via unichrome driver at the moment. As a workaround, you could always use the vesa driver instead of the via one. That would prevent the lock-ups. However, opengl performance would suffer when using the vesa driver. Btw, you can also paste your logfiles and debug output snippets into files and use the "attach file" option. That makes the comments a wee bit more readable.
