(ACPI) System shuts down on boot with Critical Temperature Reached (23C) Shutting Down

Description of problem:
Gateway M675 Laptop with Pentium 4 2.80 (HT); 512MB RAM. Motherboard
(claims to be) Gateway M675 Rev 1.0 with Gateway Bios 39.01.06
12/12/2003 (Phoenix Bios in reality). Other utilities (under Win XP)
report ACPI enabled motherboard with ACPI Fans, etc. and LM90 sensor chip.
During bootup, nearly immediately, before even option of 'Press I for
Interactive Startup' the system reports Critical Temperature Reached
(nnC) Shutting Down. Reports this for 2nd CPU (a different sensor)
slightly different temperture. Echos both lines again and shuts down
system cleanly. The reported temperature is reasonable for the system
condition 23C for cold boot, 40C on a reboot after some time on.
Reported temperatures are similar to what I see when booting into XP
using other utilities and are, as you can see not sufficiently high to
require a shutdown.
Symptoms occur with rhgb on or off (prior closed bug); apm=off;
pci=noacpi; on or off battery power; with system hot or cold. Booting
with acpi=off allows system to boot cleanly and it runs with no
evidence of overheating. When running APM appears to work and reports
battery capacity correctly.
Also noted that during initial loading of Fedora Core 2 saw same
message while in text mode (while verifying media) along with
high-ASCII text, but no shutdown occurred. This is new laptop for me
so have no prior experience with Fedora C2 or C1 on this machine,
however works properly with both Knoppix 3.3 and Gnoppix 0.6.0 so
suspect will operate properly with 2.4 or non-ACPI kernel.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot Fedora Core 2 with default options on this hardware
configuration. Observe that it shuts down.
2. Boot with acpi=off and everything works fine.
Actual Results: Shuts down cleanly with reports of Critical
Temperature Reached (nnC) Shutting Down (2x).
Expected Results: Should have boot cleanly.
Can't retrieve dmesg from failed bootups; if I can get retrieve a
failed boot log I will post.
This is an interaction between the kernel acpi code and your BIOS.
1. Note that the BIOS appears to be reporting the correct (or at
least reasonable) CPU temperatures and those temperatures are lower
than what should trigger a shutdown.
2. Unable to retrieve dmesg log for startup. I can get to it, but
shutdown happens before anything is written to the log.
Recommendations for instructing grub(?) to redirect standard output
to a file?
Having the exact same problem here, but running FC3 with
2.6.10-1.741_FC3. My system is an Abit AN7 / Athlon 3000. It is
reporting 20C, which is a great temperature, but the kernel things
it's a critical temparature and it says shutting down, but will still
continue to boot, but at a low frequency (I found this because my
machine was compiling slowly). My machine is fine with acpi=off.
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat. The Fedora legacy project will be producing further kernel
updates for security problems only.
If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.
