moused + ScrollLock + reboot = fun

Hi all,

Rebooting a system while scrolling is activated on the syscons with
moused proceeds in a funny way: the system goes on with the shutdown
as usual until "All buffers synced." is printed, and then it waits
for about 5 minutes before finishing the shutdown.  Any ideas about
what it waits for?  Pressing the reset button during the pause
results in dirty file systems, which means they were not unmounted
yet.  No moused or no scrolling = no pause, reboot normal.
