Using kernel 2.0.25 patched with Werner's ATM drivers
at version 0.26, we experienced the following.

Untroubled normal operation, but when the machines were
left for an amount of time (>several hours) it was noticed
that they sometimes started to thrash the hard drives for
no apparent reason.

This thrashing would continue until the machine was reset.
During this time, it was not possible to interact with the
OS (no logins or anything).

We have now upgraded to 2.0.29 and patched with 0.28 of Werner's
