IBM ACPI extensions hosed after updating ACPI

Description of problem:
After upgrading to kernel-2.6.12-1.1420_FC4, there is no
"ibm" entry in "/proc/acpi" anymore. Curiously, there is
still an "ibm_acpi.ko" module present in "/lib/modules/2.6.12-1.1398_FC4/kernel/drivers/acpi" but
it cannot be loaded.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install "kernel-2.6.12-1.1420_FC4".
2. Boot up system.
3. Check "/proc/acpi".
Actual Results: The IBM extensions to ACPI are not available.
Expected Results: The IBM extensions to ACPI should be available.
Compiling "ibm-acpi-0.11" forthis kernel version leads
to the following compilation error:
make -C /lib/modules/2.6.12-1.1420_FC4/build SUBDIRS=/home/install/build/ibm-acpi-0.11 modules
make: Entering directory `/usr/src/kernels/2.6.12-1.1420_FC4-i686'

It seems that "ibm-acpi" has not been updated to work with
the ACPI update of 20050729.
Sorry, I obviously meant to write:
"Curiously, there is still an "ibm_acpi.ko" module present in
it cannot be loaded."
Can you try the errata kernel in updates-testing please ? That has an ACPI
update which may fix your problem.
*** Bug 167078 has been marked as a duplicate of this bug. ***
To which errata kernel in updates-testing are you referring? There are a few,
and all are lower release numbers than kernel-2.6.12-1.1447_FC4 (which has the
same issue, as noted in Bug 167078).
That comment was made before 1447 got pushed to final updates.
Yes but the problem persists with 1447 (on my Thinkpad X40)

FATAL: Error inserting ibm_acpi

No improvement for ACPI updates of kernel-2.6.12-1.1450_FC4. The "ibm-acpi"
package (v0.8 to v0.11) seems to lag behind and needs to be adapted to the
current ACPI trunk.
FWIW, the ibm_acpi.ko loads just fine under the 2.6.11 kernel that was released
with FC4. All errata kernels numbered 2.6.12 break this.
Are you sure? It worked perfectly for me (T41) from kernel-2.6.11-1.1369_FC4
$ uname -r
$ lsmod |grep ibm_acpi
ibm_acpi 15997 0
$ dmesg | grep ibm_acpi
ibm_acpi: IBM ThinkPad ACPI Extras v0.8
ibm_acpi: dock device not present
But it broke for me when I installed kernel-2.6.12-1.1447_FC4. Obviously, it
broke for the OP at kernel-2.6.12-1.1420_FC4 (which I never tried).
Nope, not sure at all. :-) I think I tested the other three kernels but missed
this one. I can indeed confirm that the included 0.8 ibm_acpi as well as the
0.10 from the web site both load fine in 2.6.12-1.1398.
Sorry for the incorrect info.
Issue resolved for kernel-2.6.13-1.1552_FC5. "ibm-acpi" received an
update from Len Brown (v0.12a). Will hopefully apply to FC4 as soon as
2.6.13 is considered stable enough.
This bug persists 2.6.12-1.1456_FC4 as tested on my thinkpad x40, which means I
keep running kernel 2.6.12-1.1398_FC4. Is there a workaround for this, or
should I wait for kernel 2.6.13?
There's a preview of the 2.6.13 kernel in updates-testing right now if you want
to try that (though it may have other problems too right now, which is why its
in -testing, not -final yet)
I can confirm that using kernel-2.6.13-1.1524_FC4.i686.rpm from -testing
restores the ability to load the ibm_acpi module. Tested on an ThinkPad T30.
Same here on T41. So far (after the latest updates-testing
selinux-policy-targeted) it looks like all functionality is restored. From the
boot messages, it looks like there have been some changes in ibm_acpi. Do they
Mass update to all FC4 bugs:
An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream
kernel (126.96.36.199). As there were ~3500 changes upstream between this and the
previous kernel, it's possible your bug has been fixed already.
Please retest with this update, and update this bug if necessary.
Apparently fixed in 2.6.13-1.1526_FC4.
After upgrading to 2.6.13-1.1526_FC4, /proc/acpi/sleep no longer exists, so I am
no longer able to suspend. I have no problem with 2.6.12-1.1398_FC4.

See bug #169200. Not sure how we were all supposed to have divined this change,
but that solution works fine.

Yes, that works. Thanks!
