Hi, people (and Zhao in particular).

I'm adding a CC to the people in linux-kernel as we may, perhaps, get  
some ideas of how to debug this year long bug.

Pardon me as I'm not sure how many ways to resume a box are. I'm not  
familiar with hardware matters.

Well, this didn't work the last time I tested. Actually, just to  
recap, I have never gotten Linux to resume this notebook at all. With  
kernel modesetting, without, just booting with /bin/bash as init etc.

The unfortunate fact is that its warranty has just run out. I am  
really interested in getting it working, as I do need this for some  
development.

The sad thing is that Windows Vista that came pre-installed with it  
supports both suspend-to-ram and suspend-to-disk without any problems  
at all, but I'm not sure what to do, as I don't know how to use  
Windows (and I'm not really willing to learn a non-Unix Operating  
System). :-/

I made sure that I bought a notebook with an intel chipset, but it  
seems that this isn't exactly sufficient to get a machine properly  
working with the kernel.

That being said, while I am not willing to learn how to work with  
Windows Vista, I am open to trying some, perhaps, invasive tests  
under Linux.

Well, actually, if there is any debugger/tracer/whatever that I could  
run under Windows Vista and that can reveal important information,  
then I'm ready to go.

Any ideas, anyone?

Thanks, Rogério Brito.
