acpi stopped working for me sometime after 2.6.11

acpi stopped working for me sometime after 2.6.11

[Philip Walden]

I just upgraded from RH9 to FC4. The the distribution CDs I used 
provided 2.6.11-1.1369_FC4.

The upgrade was successful and I was happy to see ACPI actually power 
off my machine when I did a shut down. Something I had missed when I 
went from XP to RH9.

My next step was to upgrade using yum. This jumped me to 
2.6.17-1.2139_FC4. ACPI was now disabled in boot up.

After several days of poking araound doing before and after compares I 
found something that works.

I added an acpi=force kernel parameter. ACPI loaded and shutdown now 
powers off the box.

Yeah!

I spotted the work-around in another thread where it is used to get 
around the ACPI BIOS age cutoff.

Not sure what happen after 2.6.11, though.

Does anyone care what happened? Should this be reported as a bug?

The motherboard, I am not sure what it is. The box is a HP Pavilion 
9695C. The closest I can get to a specification for the motherboard is:

with AMD Athlon Processor and an AMD Irongate (AMD-751) Chipset".

Here is a dmesg excerpt showing the dissabling message.

Please open bug in bugzilla.kernel.org and attach full dmesg to it.
