Well, that could cause hangs, but I'm seeing the same symptoms with
1.4P, and a few other people have posted "me too" about this happening
to them.  Maybe all of our CPU fans have y2k bugs? :-)

Every time my system has hung with 1.4P it has been during a "make
build" -- high disk IO and lots of process creation.

Under normal load the system is fine.  High CPU utilization by itself
doesn't seem to trigger it.

This machine is a Pentium III.  dmesg output is appended.
