Description Ken Barber 2007-02-24 20:25:06 UTC
Description of problem:
Immediately after loading, kernel 2.6.19-1.2895 shows this message

Critical temperature reached (128C), shutting down

on startup after bringing my laptop in from cold weather (i.e., after coming
home from work).  Kernel 2.6.18-1.2869 does not have this problem.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.  Walk around in cold weather with laptop in bag
2.  Come inside, sit down, plug in laptop
3.  Boot laptop
Actual results:
"Critical temperature reached (128C), shutting down" very early in the boot
process (usually just after the "Red Hat Nash version ...." displays)

Expected results:
Laptop continues booting

Additional info:

Workaround:  boot into kernel 2.6.18-1.2869 and use it for a while until the
laptop gets warm.  Then reboot into kernel 2.6.19-1.2895 and it will work fine.

I have not yet tried this with kernel 2.6.19-1.2911 as it has been nice all week
here (I'm in Nashville, Tennessee, USA).  If you want, I can put the laptop in
the freezer for a while and see what happens.

That happens on my V2000 as well.  Updating the BIOS seems to
have made it quit, but I needed to install XP to do that.

Comment 2 Ken Barber 2007-03-30 02:52:40 UTC

This bug still exists on my laptop, in all subsequent kernel versions 
including 2.6.20-1.2933.fc6.

I have updated the BIOS.  It made no difference.

Since kernel 2.6.19 is no longer available for FC6, I now have to boot into 
SuSE to warm up the processor.

Comment 3 Chuck Ebbert 2007-03-30 14:31:32 UTC
Can you try adding these lines to /etc/modprobe.d/blacklist:

blacklist k8temp
blacklist hwmon
blacklist k8_edac
blacklist edac_mc

Spring has arrived where I am, so I had to put the laptop in the refrigerator 
to test it.  I only tried it once, but it booted normally.

Do you want any log files?  Do you want me to remove some of the above from 
the blacklist to narrow down the problem?

Yes, if you can narrow this down it would help. I would guess that
it's not the k8* drivers, but really can't say for sure.

Hi.  It's summer now, I have upgraded to Fedora 7, and I had forgotten all about
this bug.

I put my laptop in the freezer just now to see what would happen.  It boots fine
into FC7 with 2.6.21-1.3228.fc7.

Do you still want to pursue this bug?  I still have FC6 installed in a different
partition -- and it still fails when the laptop is cold -- if you still want
t-shooting info.

Comment 7 Ken Barber 2007-08-21 21:54:16 UTC
I will be giving my laptop away in about a week.  If you want troubleshooting
info, you need to ask for it now!

(This is a mass-update to all current FC6 kernel bugs in NEW state)


I'm reviewing this bug list as part of the kernel bug triage project, an attempt
to isolate current bugs in the Fedora kernel.


I am CC'ing myself to this bug, however this version of Fedora is no longer

Please attempt to reproduce this bug with a current version of Fedora (presently
Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a
few days if there is no further information lodged.

Thanks for using Fedora!

Comment 9 Ken Barber 2008-01-15 00:13:36 UTC
Can't do it.  I no longer have the laptop.

Comment 10 Jon Stanley 2008-01-15 01:27:27 UTC
In that case, I'll close this bug as INSUFFICIENT_DATA
