I am experiencing abrupt and uncommanded power off on my T61 notebook.
It appears to be correlated with the upgrade to the 2.6.28-16 kernel.
2.6.28-15 seems to be stable.

Before I file a bug report I want to see if anyone else has seen this
behavior.  I know it is not a temperature or fan issue.  All the
temperature sensors are within normal range.  I also blew all the dust
out of the ventilation system just to be sure there was adequate

The problem is a bit difficult to debug, since nothing unusual appears
in any of the logs which is not a surprise, since the machine just
powers itself off.
