How to troubleshoot this? F16 x64 laptop - wake after suspend

Howdy,

with any 3.2.x kernel (3.1.x are ok) I have the following problem on my vanilla Dell Latitude E6410: after suspend to RAM and wake up the screen stays blank/black, no mouse. I assume that the rest of the wake up process works as I can CTRL+ALT+F2 into new session (without seeing it on the screen obviously), log in and reboot.

I've got multiple kernels installed - problem occurs with any 3.2.x kernel, not with 3.1.x or earlier. The system is a fully up to date F16 x64.

I didn't find anything suspicious in /var/log/messages or pm-xxxx.log. The only thing possible related is in /var/log/gdm where I find quite a few of

Any ideas how to start troubleshooting this? Which logging to set up?

Thanks

After more digging I actually found something in the logs:

<3>[ 972.783664] [drm:intel_dp_complete_link_train] *ERROR* failed to train DP, aborting

Googling for this gives http://forums.gentoo.org/viewtopic-p-6941142.html . According to those guys it's a kernel bug that'll be patched in 3.3 and 3.4.

# this should bump you up to kernel 3.3.x
yum -y install fedora-release-rawhide
yum -y install kernel --enablerepo=rawhide
