kernel-2.6.18-1.2200.fc5 - cooling fan powers off at boot time.

I've got a problem booting kernel-2.6.18-1.2200.fc5

I'm using an eMachine T2240 system. 
CPU:  CPU, CEL-2.2G/128K/F400,mPGA478,SL6RW CPEMIN100155 
CPU Fan Type:  Fan, H/SINK:117162CBL01,MPGA,P4P-2.4G,W/

(The above was collected from: 
http://parts.emachines.com/emachines/sys_lookup.asp )

When I boot the 18-1.2200 kernel the CPU cooling fan power off as the 
words, “Uncompressing Linux Kernel....Ok booting kernel.” appear on the 
screen.

Prior to this kernel I've had a problem where the fan will power off when the 
CPU heats up too much. That still occurs with kernel-2.6.17-1.2187_FC5 and 
earlier. But now with  kernel-2.6.18-1.2200.fc5 the fan powers off 
immediately at boot time.

Is there something I can do to correct this problem. I'm admittedly not 
particularly knowledgeable in this area.

Thank much for the help.

James.

In order to troubleshoot this - you'll first need to determine if this
is or is not a hardware issue. Is the cpu shutting down because of
overheating?

If not, which kernel can you use without problem? Then compare the boot
up parameters - between the working and non-working kernels. Sometimes a
kernel may fail to load a module. Often you'll find that some kernels
will work better with your system than others.             --------gary

I have the same problem with my acer laptop, it seems that the acpi support
in 2.6 kernel is at the moment a bit buggy, if a programmer reads this list,
it would be greatly appreciated, that this got fixed, laptops under linux
are at least 10 degrees of celsius above a windows installation...

ive had this problem not only with my own acer, but with other laptops
too... not all though, so i think its a problem with the definitions of acpi
devices...

i have an acer tm 250 btw.
