On my Fedora 11 powered EeePC I have:

kernel-2.6.29.4-167.fc11.i586
kernel-rt-2.6.29.5-1.rt21.1.fc11.ccrma.i586
kernel-rtPAE-2.6.29.5-1.rt21.1.fc11.ccrma.i686

Both rt versions fail. Is it possible, using yum, to re-install the 
previous released fc11.ccrma kernel-rtPAE version ? That one was running 
ok.

That helps. I can now see a last message before my screen goes black. 
The problem seems to be in this error message:

"EXT2-fs: dm-0: couldn't mount because of unsupported optional features 
(240)."

I have no idea what this means. But it doesn't look very good. 
It only happens on my EeePC. On my other laptop I have installed the 
latest fc10.ccrma kernel-rt version from the testing repo and it works 
fine.
