Lenovo thinkpad T400 suspend problems

[japafi]

Hi.
I have Lenovo Thinkpad T400 with 2.6.35.10-74.fc14.x86_64 kernel
Sometimes my system fails to enter suspend state. The process starts, but gets stuck just before "turning lights off" and the suspend indicator will be left blinking.
I tried to search bugzilla, but apparently lack the skill for proper searches.
This is not the problem with tpm module, which have been referred in some of the suspend problem cases.
I did not have suspend issues with F13 so this is something introduced by F14 kernel releases.

What is the "right way" to install latest test kernels?
I'd like to see if those would fix the issue.
Excluding the fact that those kernels may have some bugs, are there other issues with kernel <-> fedora release version that may cause problems and that's why one should avoid installing test kernels?

btw. How long does it take to hibernate? With current system (4gig ram, 8gig swap, all but boot encrypted) I think it's faster to shutdown and restart than to hibernate and wake up.

I have a t400 and went from F12 to F14. I've always had intermittent hibernate problems, but with F14 I also could not suspend. I installed a recent kernel from Koji and I have since had no suspend problems and almost no hibernate problems.

So the kernel I installed is:
2.6.37-2.fc15.x86_64

I googled koji to find it. Once on the summary page type kernel in the search bar at the top, you will then see a column of recent builds. Scroll down till you find the build I posted above, click on it and it will open to a list of the various architectures available. Download the kernel, kernel firmware, kernel-headers and kernel-devel to your /var/tmp directory.

Then do: ( as root "su -")

# yum --nogpgcheck localinstall /var/tmp/kernel*

to install your kernel. This assumes that you haven't downloaded any other kernel to that same directory.

Found out other instructions on updating, so yesterday I did:
yum --enablerepo=updates-testing update kernel kernel-devel kernel-headers

Now I', at 2.6.35.11-83.fc14.x86_64
Lets see how this one works. At least this is "designed" for F14.
