My laptop can't finish boot with systemd-28-4.fc16 and kernel-3.0-0.rc2.git0.2.fc16 - the boot
process just stops at random points and CPU usage goes high.

systemd-28-3.fc16 and kernel-3.0-0.rc2.git0.2.fc16 - did not have this behavior.

The only possible way to boot is to add "selinux=0".
Especially for Daniel J Walsh, the addition of "enforcing=0" doesn't make any difference - boot stops.

Thanks.

Last time I had similar problem, ended up:

rpm -e --nodeps selinux-policy selinux-policy-targeted
yum install selinux-policy selinux-policy-targeted
touch /.autorelabel; reboot

and then all was ok.
ymmv.

In my case relabeling did not help at all.

Did it, there is no any kind of debug messages on the screen.
Boot process just stops.

I updated to libselinux-2.0.102-6.fc16 and boot starts to go faster, but any way after few
successful times, it starts to stop again.

Did you also remove "quiet" and "rhgb" from the kernel cmdline? If you
leave that in all output will not be visible.

Actually I never use them ("quiet" and "rhgb"), I prefer to see what is going on, and that is why I
know where the boot stops. There is no any debug or error messages.

May be I know what is going on. May be I did something.

I will let you know latter.

Thanks

Are you sure it's not doing an fsck? (There's an open bug for that.)

FYI I have the same problem on my box. Was waiting for fixed 3.0 kernel
packages to report a bug. I suspect some kernel/systemd mismatch

I checked it again - it is not me.
Boot stops at random points - for example last time it stops at:
"Configure read-only root support"

So it can't even relabel FS, because it happens mush farther.

But option "selinux=0" solves this problem.


Thanks.

I'm having the same problem with an i686 Rawhide virtual machine
(using KVM, on a Fedora 15 x86_64 host). The last few lines I see
before the hang are these:

Started udev Kernel Device Manager.
Starting Stdio Syslog Bridge...
Started Stdio Syslog Bridge.
Started udev Coldplug all Devices.
Starting udev Wait for Complete Device Initialization...
[ 9.542951] EXT4-fs (dm-1): re-mounted. Opts: (null)
Started Remount API VFS.
Started Remount Root FS.
Started Apply Kernel Variables.
Starting File System Quota Check...
Starting Configure read-only root support...

At that point output stops for awhile. The "CPU usage" graph on
virt-manager jumps up to about 25% to 30% (eyeballing it), and the
"Disk I/O" graph drops to zero. If I leave it like that for awhile to
see if anything else will happen, I eventually start seeing messages
about CPU stalls.

Just in case it is relevant, earlier in the boot, I see this:
