 Note that for me the problem exists with 5.1 (and earlier 5.x) as well 
 as current.

 If it helps to try and track down a particular driver that might be 
 causing the problem I've put dmesg outputs for optiplex760 and 755 
 (that have the problem) and latitude e6400 (that doesn't) at
 http://homepages.ecs.vuw.ac.nz/~mark/dmesg.
 {optiplex760,optiplex755,latitudee6400}
