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):
http://kernel.ubuntu.com/~kamal/scien+i915bri/
** Summary changed:
- Dell Studio 1558 (Arrandale) hangs on resume from suspend
+ Various machines hang on resume from suspend (SCI_EN)
