Here's another "me too". My box just froze when copying a large amount of big files over the network to my machine, causing heavy disc access and lots of interrupts. Curiously I just updated my box to 4.4-STABLE from 4.3-RELEASE and it hasn't occured before.
Though in my case the box is quite old (dmesg attached) but is using a relatively new IDE disc. -Richard
