I have only seen two instances under 2.6.14.5, and none so far under
2.6.15. I do not know how to reproduce the problem. I suppose that it is
a rare race condition showing up?
In case you are wondering, this has been, and I believe still is, rock
solid hardware: that is, not over clocked or marginal in any way. It
normally runs the latest even series released kernel. So it has run
under 2.2.*, 2.4.* and now 2.6.* kernels reliably.
I append the other case logged under 2.6.14.5 in case it throws any
extra light (which I doubt)
