suspend/resume moused restart required

Is the kernel and userland in sync? Maybe moused just needs a recompile 
because of the changes to the psm driver.

Do you have "hw.psm.synaptics_support" and/or 
"hw.psm.trackpoint_support" enabled in /boot/loader.conf?

Also, could you try to set "debug.psm.loglevel=2" in /boot/loader.conf 
and post the dmesg log after a suspend/resume cycle? Similarly, running 
moused manually in the foreground with "moused -dd -f -p /dev/psm0" 
might show some useful info. Maybe the psm data gets out of sync somehow.

Can you reproduce the problem when X is not running?

You might also try to revert the latest changes to psm.c and mouse.h and 
see which commit causes the problem: 
https://svnweb.freebsd.org/base/stable/10/sys/dev/atkbdc/psm.c (r281708, 
r281709, r281964). Both kernel and moused need to be recompiled.

Cheers,
Jan
