Public bug reported:

On boot I have two sets of sensors (coretemp and acpi) both of which
report reasonable temperatures, also the Fans respond to load and keep
the machine alive.  Following suspend/resume cycle the acpi temperature
sensors stop reporting anything other than 0c and the fans no longer
respond to load leading to hard power off on overhead.  Fail!

I have managed to confirm this is present back at least to -11 kernels,
I could not suspend/resume the -7 kernel I happen to have.  Karmic was
not affected.
