Yes, I also see those "device reopeded" messages.

I dunno what to suggest, if those errors are "fine" and unrelated to the 
problem of the ps/2 keyboard freezing I can only think in two possible 
suspects: kernel or xorg.

You can:

1/ Start the system with no xorg (console) and leave it so for sometine 
to check if the problem is still present (even with no x server).

2/ Review you kernel log, just in case ("cat /var/log/kern.log | grep 
input").

If this is something related to X server, as a workaround to avoid 
restarting the system when this occurs, you can restart gdm3 service ("/
etc/init.d/gdm3 restart").

I would not discard to open a bug report.
