If this only happens after a period of activity, it could be caused by the system paging heavily and paging out the X11 server. > - hard-disk is slow and is unusually active > (portupgrade needs about 15 minutes till > it arrives compiling first port) Do "vmstat 10" or "iostat 10" show an unusual amount of disk actvitiy? If so, the system could be slow because the disk is saturated. Is there anything that triggers this behaviour? Do you see a lot of activity when the system should be idle? If you are seeing a lot more disk activity than normal, there is some other problem besides interrupts. > - syncer is slowly counting vnodes down and needs > a few seconds till it arrives at 0 This is normal. The syncer now syncs the file systems before it shuts down instead of immediately shutting down and deferring the file system sync to a later stage of the system shutdown.
