Hi,

I got a bug report against pm-utils-1.1.2.3 [1], where a user complained
 about failing suspend/resume on his DELL X200 (which uses the i915 driver).
Apparently he requires quirk-vbe-post and quirk-vbemode-restore, which
is filtered out by 98smart-kernel-video though.

Can someone with more knowledge about intel hardware and its kernel
modesetting driver please comment on the current status of this driver
with regard to quirk handling and which one should be applied or
filtered out.

As it seems the current logic in 98smart-kernel-video is not
sophisticated enough.


Cheers,
Michael

It's the i915 driver from the 2.6.26-1-686 kernel.

If you're referring to the X driver, it's "intel" driver version
2.3.2 (xserver-xorg-video-intel 2:2.3.2-2+lenny2).  But, I didn't
think the X driver was relevant since the same thing happens in a
text console.

Nope, I did try those - it puts the machine into an unrecoverable
state and requires a hard reboot.


For a long time I thought *none* of the quirk options worked since
I had no indication that they were being ignored, when I was
testing with pm-suspend --quirk-....  It was only when exploring
the hook directories that I accidentally discovered the
98smart-kernel-video file.  At the very least, it would help if
this behavior were documented.

Thanks,
Karl
