I have done come test of the new suspend/resume capabilities.
However suspend failed to correctly work on my laptop (dell d630).
You must note that there is a few trouble issues with sound on this laptop:
the snd_hda_intel driver correctly detect a STAC9205 and get the default
pin configuration from the bios. So far, so good ... however, pin B is by
default configured as line out and is working as such. But, it does not
correctly work with an external microphone as it need a vref. So,
instead of using the
bios settings, I use the windows default settings. This is not perfectly
working : I usually get some glinches that disappear after a logout/login
procedure. Nothing significant appears from a diff between
before and after this procedure ...
Now let talk about the suspend failure. The suspend procedure (which was
working) produce a bug (I was not able to catch the message at this
stage. This is a
partial and hand written report ..):
Bug: unable to handle kernel NULL Pointer deferred at virtual address 0000

By the way, I am running mandriva 2007.1 with kernel 2.6.17-14mdv.
