@Michael:

Guess your solution is a non-solution here:

[258486.793395] i8k: not running on a supported Dell system.
[258486.793415] i8k: vendor=Hewlett-Packard, model=HP Pavilion tx2000
Notebook PC , version=F.08
[258486.793430] i8k: unable to get SMM Dell signature
[258486.793441] i8k: unable to get SMM BIOS version
[258486.793471] Dell laptop SMM driver v1.14 21/02/2005 Massimo Dal

As I mentioned, as valuable your workaround (because letting the fans
run at max is not a solution, it's workaround), it only applies to users
that can control their fan.

As it is a workaround that applies only to part of the people having
problems, it's best left as a workaround in the issue that people having
troubles can apply.

As to your assertion that it's easy to reproduce, it's obviously not.

There are about 100 people following this issue, merged from most if not
all heat related problems on launchpad.

So even if only 1% of the users report their problems, that's around 10k
systems that have this problem. While no one knows for sure, the number
of Ubuntu systems is probably way bigger than 1M.

Basically it's a very tiny slice of the market. Hence very hard to
reproduce and fix. Especially as a description "my laptop shuts down
because temperature problems" is basically useless. It can because the
fan runs to slow. It can because the CPU enters not enough low power
states. That can happen because of a bug in the kernel. Some userland
problems. It's the equivalent of "doctor please help, I think something
is hurting me somewhere, but not sure". (the not sure part comes from
the fact that some of the issues might be coming from real hardware
problems)

While now the doctor tries to figure out what the problem is, your
reaction is "stupid doctor, does nothing, why does he not give this poor
guys the pills that helped me last week? Guess I need to change
doctors!"

And if you prefer Fedora it's your right to go there and pester them.
