Hi all,

with kernel-image 2.6.8 I could send my IBM R40 into suspend using apm and resume
afterwards without a problem. Since using kernel-image 2.6.9-686 the laptop still suspends and resumes, but right after the machines wakes up it behaves really strange: all the icons on my KDE desktop flicker when moving my mouse and using the keyboard ends into the following error messages on the console (pressing ALT-F4): 

....

Only rebooting my IBM laptop solves this problem as far as I can see.

You can find the boot messages of kernel 2.6.8-686 and 2.6.9-686 here:

http://www.morbitzer.de/tmp/boot-2.6.8-686.txt
http://www.morbitzer.de/tmp/boot-2.6.9-686.txt

As I said, suspending and resuming my laptop with 2.6.8-686 works fine.


Hi,

Thanks for the bug report.

I took a quick look and unfortunately there seem to
be quite a lot of changes to atkb.c between 2.6.8 and 2.6.9.
It is a bit hard to tell which change might have caused this
problem.
The only thing I found that may help is http://ozlabs.org/pipermail/linuxppc64-dev/2004-March/001315.html 
but it seems like a long-shot at best.

I have CCed the maintainer + linux-input mailing list in
the hope of some help.
Does this still happen with 2.6.10 or 2.6.11-rc3? If yes, please use 
i8042.debug=1 on the kernel command line to get a trace of the
communication with the keyboard in the kernel messages.
Sorry for answering so late, my wife was on holiday and took the laptop with her ;-) !
It still does happen with Debian Kernel 2.6.10-1-686 (2.6.10-4). When using i8042.debug=1 on the kernel command line I get back "Unknown boot option `i8042.debug=1': ignoring", am I doing something wrong?
It is difficult to describe what's going on after the resume, the keyboard simply behaves strange. When I press the "s" button it keeps printing the "+" character, when pressing the shift-key, it keeps printing the "E" character (in a terminal window or any editor) etc. etc. 

In the syslog I can see these lines again:

Let me know what else I can test for you. If it helps I can give you ssh access to this laptop. 

Regards, Jörg.
