            Bug ID: 261641
           Summary: vt newcons together with KMS modules: Wrong cursor
                    positioning when kldloading KMS
           Product: Base System
           Version: Unspecified
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: sblachmann@gmail.com

I noticed that when radeonkms gets kldloaded while the cursor is on the last
screen line (of 25x80 mode) after lots of output, it appears to place its
message "Loaded radeonkms, id 14" onto screen line 25 *after* resizing the vt
screen to a higher resolution than 25x80, overwriting previous output.

Shouldn't it output on the last line at the bottom instead, where one expects
it to appear, instead of somewhere into old output in the upper half of the
screen, where it is easily overlooked?
