The machine is still functional and if I log in over the network I can do anything I like, including killing the X server and the display will never alter. It also seems that the system is accepting keyboard input because when it freezes I can cat information to a file (if the mouse was over an xterm) and verify over the network the file contents. Nothing unusual appears in dmesg when the lockup happens. The last kernel I booted successfully on the system was 5.0, so I'll try compiling 5.1 to narrow down the changes. James
