Hello Andriy!

I remember we were discussed that problem before, can you please check if moused enabled (in rc.conf or by devd for USB mouse) and do you use Kern.vt.textmode (IIRC its name)?

Mousecharstart is a first char of 4 to replace its bitmap with parts of mouse pointer. You can see its job by defining it to some of frequently used chars, then mouse pointer will be moved over many chars on the screen :-)

About second question - there is no problem to just remove that warning, but think better to left it to make an idea for developers about what term ioctls doing with sysmuse devfs node.

Thanks for testing!
