Using MIT's R4 xdvi on our MIT Xqdss colour VAXes often hangs the display.
Killing the X server gets things going again. Echoing "xxx" to
/dev/console also unsticks things, but the system enters a
semi-comatose state. A bunch of these appear in the uerf log:
EVENT CLASS OPERATIONAL EVENT
OS EVENT TYPE 250. ASCII MSG
SEQUENCE NUMBER 573.
OPERATING SYSTEM ULTRIX 32

FIRMWARE REV = 1.

and the kernel becomes very sluggish:

What is going on, and how can I fix it? The only way out of this
seems to be a reboot.
