Comment 6 for bug 283126

The driver of some device can't handle the suspend/hibernate event as expected from our investigation.
After upgraded to Intrepid final, we can't reproduce it on HP-2230s.

But I can still reproduce this issue on SONY Vaio VGN-Z540. There's a patch fixing this bug for the SONY laptop which already in kernel 2.6.28-rc3:

    sony-laptop: ignore missing _DIS method on pic device

    At least the Vaio VGN-Z540N doesn't have this method, so let's not fail
    to suspend just because it doesn't exist.
