2.2.18 has significant VM problems which make it unsuitable as a base.
2.2.19pre3 or later is enormously preferred.  2.4 patches will be
available in the future, but are not ready yet.

It causes a kernel OOPS in response to a detected bug condition,
forcing the kernel to generate a stack backtrace on the syslog telling
us where the problem was detected.  2.4 kernels have a generic BUG()
macro which achieves the same end.
