I'm on an X200s, running Debian Sid.

I use primarily a text-mode interface, so can't speak to the mouse,
but I do see regular 1-3 second "freezes" of the display when typing
or issuing commands in the shell...all of a sudden I'll find myself
"blind-typing" for 3 seconds or so before a backlog of characters
burst onto the screen.

I wrote to this list a while back regarding the problem [1], and more
recently to debian-users [2], but can find no solution. One clue: the
behavior rarely shows up while plugged into AC -- I primarily see
these freezes while running on battery.

IMO, the way this interrupts flow makes for a barely usable computer.
