That might be. But that might be a second step, to find the actual
cause. I think first the patch that causes the problem should be
fixed/reverted to have a working kernel and the next step would be to
find the real cause.
I would happily help to solve both.

descriptions. ;-)

Oh, I would be happy to be able to provide that. But if you look at the
first mail in this thread, I asked days before how to debug that cause.
The problem is that it stops in the middle of the suspend right after
switching of screen. There is no way to get it back working after that
and so no dmesg. I have to hard switch off the laptop after that.

One another account to just fill one bug? Or is there a way to fill the
bug without creating an account? I would really like to not create
another account. I still have that many from systems that forced me to
create an account for just one bug report.

[PATCH]
Yes, I can do that. But can you tell me how to get dmesg output when the
problem happened? After that the box is unusable and I have to hard
switch off it. There is no way to get any dmesg output after the bug
happened.

Ps. I can forward the first two messages that I posted on kernel ML.
That should also be available online.
