@IanG and @zeddock, care to open new bug reports? It's likely this
issue is hardware specific. Janne, the original bug reporter has
commented this appears to be resolved for Intrepid. Thanks.

You'll need to enable the Intrepid repository to get the 2.6.27 kernel.

Well said Janne. This has been a terrible kernel for overheating issues

With 2.6.24-19-generic SMP, the temperature is 64 degrees.

This is at least one difference between Gutsy and Hardy. Gutsy was using

It seems the heating problem is a red herring, a false lead, an
unrelated distraction.
It seems that the 2.6.22 and 2.6.24 kernels running the machine hot is

As I've described above, the kernel itself is not the cause of the

A few more notes:
* The enormous number of wakeups from the USB subsystem can still be
triggered without unplugging a mouse; it is a lot less frequent though.
* The kernel still locks up.
* This kernel bug seems to be the same as #204996

I rebooted with power plug, wired network cable and USB mouse plugged
in. Screen blanking and so on disabled. No applications running except
for a gnome-terminal and a bash one-line loop to record temperature
every ten secondd, and occasionally powertop. Temperature stays normal,
at about 50 degree
More testing. Just booting the machine (into the Feisty kernel) and
running stuff works just fine; the machine stays at around 40 degrees.
Even when playing a movie full screen it does never go over 60 degrees
or so. This is the normal behaviour from Feisty.
If I run "powertop" I get decent values
A small addendum: The machine is running too hot with both the Hardy
