Ubuntu 10.4 Lucid Kernel 2.6.32-24-generic-pae No wake from USB

[Dion]

Package - LIRC
Release - Ubuntu 10.04 LTS
Version - 0.8.6-0ubuntu4.1
Expected Result - Able to resume from S3 by USB

Actual Result -

No power is provided to the USB IR transceiver, when you press any button on the remote once it is in an S3 state you get nothing. It appears as though all power has been cut to the USB ports.

If I revert to an earlier Kernel it works fine and you can r esume by USB IR transceiver from S3

sudo apt-get install linux-image-2.6.32-22-generic linux-headers-2.6.32-22-generic

As a second note when you revert Kernels you get no sound on resume and to get sound back you need to reboot. I have tried restarting alsa by command but this does not work.

Hi Dion,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/daily/current/ . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 614632

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Hi there, thanks for getting back to me I will try the mainline kernel but I think it has the same bug.

There is an active thread on another forum which seems to suggest it is an upstream kernel issue

http://forum.xbmc.org/showthread.php?t=76944&page=3

http://marc.info/?l=linux-usb&m=127970476426245&w=2

One other question as follows,

1) I was reading that the daily builds do not include a desktop is that correct?

Thanks!

[Dion (limenet)]

Looks like this has been committed to the upstream kernel

http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.32.y.git;a=commitdiff;h=9ba6cac516c3ed804241b7ced552a3ad60a21a06;hp=768c810fdef3421ad80a2637b789b3f79d80e9cb

Its also being discussed on the XBMC thread.....

Any ideas if this patched is being loaded in maverick / lucid?

Thanks!

[Holger Reichelt (holger-dooy)]

I can confirm that this is a big regression since the implementation of this patch: http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.32.y.git;a=commit;h=5f677f1d45b2bf08085bbba7394392dfa586fa8e Meanwhile the author of this patch commit a fix (see post above). Please apply this patch to the next Lucid kernel.

[Dion (limenet)]

Any ideas if this is being dropped into maverick / lucid?

[Holger Reichelt (holger-dooy)]

The issue has been adressed in the latest pre-proposed kernel 2.6.32-25.43~pre201008210902 from here: https://launchpad.net/~kernel-ppa/+archive/pre-proposed

With this kernel USB wakeup is functional again. Chances are that we will see this kernel in the main repo soon.

[Dion (limenet)]

Hi there, I have tried the the above mentioned proposed Kernel and it works now!

Any ideas when this will be added to the main repo?

And does anyone know if this bug is in the maverick builds?

Thanks!

2.6.32-25.43~pre201008210902 solved the problem for me as well.

[Matt (mattjs12)]

Same problem for me with lirc_mceusb IR transceiver.
Also prevents all my USB mice from waking the system too.
Confirm lucid 2.6.32-22 was the last kernel it worked on.

kernel 2.6.32-25-generic #43~pre201008250901 works

Also
kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32.17.8-lucid/ worked
But
kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.33.5-lucid/ failed
So I hope its not going to regress again going to .33!

[Brendan Cully (bcully)]

I upgraded to maverick, and it's broken again in 2.6.35-22-generic!

[hads (hads)]

This appears to have regressed in Lucid.

2.6.32-32-generic is working.

2.6.32-33-generic is not.

[fnu (fnu)]

I can confirm this issue, usb wakeup from S3 with "mceusb" did work up to 2.6.32-32. With 2.6.32-33 and 2.6.32-34, last tested today, no wakup possible from S3.

It seems that all standby power to the USB ports is switched of by these kernel versions going to S3 status. Therefore need to stick at kernel version 2.6.32.32 and will not benefit from any security patches within newer kernel packages ....

[hads (hads)]

2.6.32-34-generic was working for me, after upgrading to 2.6.32-35-generic I have lost the ability to resume from mceusb again.

[fnu (fnu)]

Same here, 2.6.32-35 doesn't bring back mceusb wakeup functionality. last kernel working for me, 2.6.32-32.

[fnu (fnu)]

Since 2.6.32-32 does really become outdated and none of the following kernels brought the abilty back, I went out and found a proper solution her:

http://ubuntuforums.org/showthread.php?t=1655836

There're maybe mor sophisticated solutions out, but I just add to the existing lien in "/etc/rc.local":

# Enable USB Wakeup
echo USB0 > /proc/acpi/wakeup

These lines:

mce_id="0815" # The id for the MCE receiver.
for i in /sys/bus/usb/devices/?-?/idProduct
do
        id=`cat $i`
        if [ $id = $mce_id ]
        then
                wakeup=`echo $i | sed 's/idProduct/power\/wakeup/'`
                echo enabled > $wakeup
        fi
done

And tested it succesfully with 2.6.32-40-generic & 2.6.32-40-preempt.
