Title:
[Intrepid] kacpid and kacpi_notify consumes all CPU after resume
--
ubuntu-bugs
This still effects my HP Pavillion a200n and 503n machines using Ubuntu
8.04.3
'kacpid' and 'kacpi_notify' must be killed by 'sudo killall' while grub
must load the kernel with the 'acpi=off' and 'apm=off flags.

[Intrepid] kacpid and kacpi_notify consumes all CPU after resume
I have no extra battery. This is a rig my son built. He knows Ubuntu; I do
not.
kacpid and kacpi_notify COME UP with Update Manager.
So long as Update Manager is up, kacpid is using 87% of my cpu.
That is not okay.
How do I reset Update Manager so it only comes up when I want it to come up?
Marking this Fix Released based on the previous comment from Gabriel,
the original bug reporter. Thanks.

Yes, Jaunty works great and hotplugging is back. I can recommend
everybody with this issue to upgrade. A word of advice is to stay away
from ext4 for now, though.
For those of you who wish not to upgrade, I unfortunately managed to
break my build system and can no longer provide up-to-date
nice, thanks. I am obtaining a new laptop anyway. Dell sucks.

I might not be the first to try, but jaunty works fine.
No kacpi* processes gone mad and hotplugging is functional as well.

On Inspiron 600m running Intrepid, 2.6.27-12 patch fixes the
kacpid/kacpi_notify problem for me when I remove my CD drive to install
extra battery. I still have the hotplug problem though: CD drive is only
recognized if it was present at boot. If it was installed at boot, I can
remove it and
Hi - for n00bs, or n00buntu's, rather - can you post the exact sudo
lines needed to access the patch, assuming your PPA is not yet in the
apt-get configuration?
For me, I had to open Synaptic Package Manager, Settings, Repositories,
Third-Party, and Add to put in your deb line, then quit Synaptic
Now that I've patched and rebooted, I'm showing kernel version
2.6.27-12. I'm also showing something like 45 software updates
available, and that a few of the security critical ones are kernel-
related for versions that are less recent - specifically, linux-
headers-2.6.27-11,
Don't despair Russ, you can install the updates you are seeing without
problems. The new kernel update is just a repack of the former kernel
released a few days ago - I think someone forgot to flag the kernel as a
security-update.
Thanks for the suggestion of improving the instructions for
Bug still present in the published 2.6.27-11 kernel.
I have merged the changes and hopefully a new kernel will be available in a few
hours.

Hey Andy. I tried out your -11 kernel and I also still get this bug.
The behavior seems to be exactly the same.
Hope this helps. Thanks.

The fix works well in that it prevents kacpid and kacpi_notify from
taking lots of CPU, but on my machine at least I can no longer hotplug
my DVD-drive or my slotin disk. They are recognised when present at
boot, but you cannot (re-)attach them later successfully. That only
works for the secondary
Based on the upstream bug report, the patch set which should resolve
this bug was applied to the 2.6.28-rc1 upstream kernel. Based on this
information these patches will definitely be available for the upcoming
Jaunty kernel. A nomination has already been opened for Intrepid. It
however looks
Since no member of the Ubuntu kernel team has had a look at this, all I
can do is speculate. I think this is the deal: the patch is not just a
few lines of obvious bug-fixes, it is a rewrite of the way the bay and
dock is handled. It removes the old bay-module completely for starters.
Because of
The -8 version with the fix was working great for me, but when it
upgraded to 2.6.27-9 the problem returned.
What gives? I thought this was fixed upstream months ago.

2.6.27-10-generic has the problem, too. With that version out, I am a
bit reluctant reverting back to the -8 version with the fix.

It certainly seems to be a Dell thing - my D620 exhibits has the exact
same issue running 2.6.27-7-generic. Using the PPA kernel solves the
problem for me. Good work - this surely needs to go into stock.

You can add another Latitude D610 affected by this. For me, its
triggered by removing the CD/DVD drive or resuming from standby. I'm
back to using 8.04 for now but I'll definitely try this in the future,
8.10 is too good to pass up. Thanks for the work you put into this

I can confirm that this but is *not* fixed in the 2.6.27-7-generic
kernel that was just pushed. Is there any way to attract the attention
of the ubuntu kernel team via this bug? My understanding is that all
that's required is for someone to review and integrate this patch for
the next kernel
Alright, I will try to assign this to the kernel-bugs team. If that is
not correct, please forgive me.
