Things like doing an ls or applications accessing files on the mounts will "hang" waiting...but I haven't seen a panel hang.  Granted, I've only rebooted the NAS twice in the past month.  Also, the home directories are not on the NAS.  How about in your case?

I tend to notice this mostly at upgrade (= reinstall) time as our 
systems each host storage which is sometimes cross-mounted on other 
systems. During a re-install systems that have the filesystems of the 
reinstalling system mounted typically show the frozen panel issue. 
People often notice this because the clock applet stops.

However, this also happens if one of our systems goes down for some 
reason when someone has its disk mounted. This seems to be worse since 
moving to sddm since it seems to cause a whole pile of home disks to be 
mounted much more than kdm.
