In an attempt to diagnose why my Thinkpad R51 completely locks up when

kernel, with KDB, DDB, WITNESS, INVARIANT*, AND DIAGNOSTIC in addition
to *BREAK_TO_DEBUGGER.  None of these things have yielded any progress
in isolating the issue.  Note that replacing the 'intel' driver with the
'vesa' driver in /etc/X11/xorg.conf does not cause the computer to
hang.  The problem appears to be specific to the intel driver.  Also, I
have been unable to get a crash report (which is what we were hoping to
see in /var/crash) regardless of the debugging options built into the
kernel.

I have attached the output of 'uname -a', 'dmesg', and 'pciconf -lv' to
this post.
It could be related to DRI, so try to disable it in /etc/X11/xorg.conf:

Section "Module"
         Disable  "dri"
         Disable  "dri2"
EndSection

Unfortunately, that did not work.

Cheers...
