Public bug reported:

Binary package hint: xorg

This is on a Lenovo T410 with the nouveau driver installed and an
external monitor connected, running 10.10.

Running kernel 2.6.37 on recommendation of a kernel developer in an
attempt to solve this problem.  Same problem obtains with stock 10.10
kernel.

Main symptom: X display is frozen, no display updates, no keyboard
response, no clicky from mouse.  Mouse cursor still moves, though.
Problem happens frequently and generally requires a system reboot to
recover.

Finally caught this while ssh'd in.  Xorg cores with the following.

[  1076.698] [mi] EQ overflowing. The server is probably stuck in an infinite loop.
