I have not seen this hang since I stopped using the direct rendering (DRI) of the ATI Mobility Radeon X1400 in this ThinkPad T60. I switched video drivers (now using the X.Org "radeon" driver) because the new external monitor I am using (ViewSonic VG2439m) would glitch, loose sync and scamble text) with the ATI driver I was using.

Until today I would resort to using the kernel magic keys to reboot the system (R-E-I-S-U-B). Today I remotely logged in from another machine on the LAN and discovered that not only was the kernel alive and all processes running, but that the "migration/0" and "migration/1" processes were consuming 50% of the CPU each, as reported by top(1). I suspect this is why the system becomes non-responsive.
