Description S.R.Mueller 2008-10-15 19:27:08 UTC

Macbook-Pro(4,1)
2.6.27-gentoo SMP PREEMPT i686 Intel Core2Duo GNU/Linux

installed applesmc (in kernel)
when booting up, apr. 30x message "applesmc: wait status failed: c != 8"

When checking the message log after login, everything looks fine.
When trying to cat /sys/devices/platform/applesmc.768/light the "wait status"-message is printed to message log.

When starting pommed-1.21 the "wait status failed" messages are printed every 20ms or so, filling up the log. After /etc/init.d/pommed stop the messages do not appear.

Searched the web and found
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/102270

I followed https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/102270/comments/36 and applied the patches in the given order.

Finally applied the mentioned http://lkml.org/lkml/2008/9/22/168 (It is not sufficient to apply this last patch, well it doesn't even work)
Rebuilt the kernel with applesmc as module and restarted.
pommed started during bootup.
Messages do not appear.

Getting a Wait Status Failed when trying to cat ../position but everything else works.

Reproducible: Always

Steps to Reproduce:
1.install gentoo-sources-2.6.27 on MBP(4,1)
2.install applesmc
3.install pommed
4.start pommed and watch message log

Actual Results:
"wait status failed"-messages are printed to the message log

Expected Results:
only an initialization message should be printed (depending on DEBUG)

Will this patchset march into the gentoo-sources?

regards,
stephan

As per policy[1], we will not be adding this into Gentoo sources. It needs to make it to the main kernel development tree.
