Here's the status with -rc3: better, but still does not work as well as 2.6.20.

3. When I switch to X (CTRL-ALT-F7), X hangs after drawing a couple of windows
   after waiting for some 10 min, I rebooted.
   no new messages showed up in /var/log/messages

In my case, I can "suspend" and "resume", but seems the clock died
after resume. "date" always returns the same time! I had to disable
CONFIG_NO_HZ and CONFIG_SYSFS_DEPRECATED in order to suspend.

Try to execute "date" and see if it changes after resume.

Thanks,
Jeff.
