Dear fellow testers,
Yesterday, I was able to connect once with the 237 kernel, I tried again, but was unable to. Today, I tried to update to todays rawhide report 20080808, but I could not connect, had to revert to
kernel-2.6.27-0.226.rc1.git5.fc10.i686 to apply the updates. I will test 238 that came in and report back later if something does not work. I ran a dmesg while not connecting:
Initializing cgroup subsys cpuset

PAT disabled. Not yet verified on this CPU type.
