Description:
I am using Kubuntu Dapper since Flight 2 and hibernate function was always working fine for me. Yesterday I have noticed that that hibernate does not work anymore - resume does not bring machine back anymore. I just get blank screen, cannot switch to text consoles or properly shutdown with Ctrl-Alt-Del.
This was the same with "ati" as well as "fglrx" driver.

Since I have pretty stuffed installation (fresh install was done with Kubuntu Flight4), including ubuntu-desktop and kubuntu-desktop, I have decided to reinstall. Since Kubuntu Flight5 is not available and install from daily build did not work (see bug 34586), I have installed Kubuntu Flight4. I have tested hibernate on Flight4 and everything worked as expected.
Then I have performed dist-upgrade and after reboot, hibernate stopped to work. If I boot in 2.6.15-15.21 kernel (Flight4), hibernate works again.
