Comment 17 for bug 553498

I have built a test kernel for Ubuntu 10.04 LTS which includes the PRELIMINARY TEST patch (written by Matthew Garrett) that enables this suspend/resume fix on any machine (I.e. this variant no longer only activates on certain machines as I described in comment #14, nor does it require any sort of manual switch to enable it). Users experiencing a hang on resume (as described above) are welcome to try this kernel. Feedback to this bug report will be much appreciated -- if you try this test kernel ** whether or not it fixes resume ** please post your result here along with the BIOS Information (Vendor and Version) as shown by "sudo dmidecode".

The test kernel including JUST the fix described above (as well as the source patch itself) is available here:
    http://kernel.ubuntu.com/~kamal/scien
To install this kernel, download the two .deb files and install them using
    sudo dpkg -i *kamal*.deb

*** Note for Dell Studio 155x users (or others with brightness keys problems and i915-based graphics) ***
I have also built an alternate test kernel which includes the fix described above, plus the fix for LP: 568611 (brightness keys):
