Steps to Reproduce:
1. Get a Dell PowerEdge 2950
2. Install F10
3. yum --enablerepo=rawhide update
4. reboot
  
Actual results:

I see this too, if I try to boot to runlevel 3.

Sometimes this issue happens too in my linux box.

Comment 3 Jimmy Rentz 2009-05-02 15:28:23 UTC 
I installed from f11 rawhide on my x86_64 system (AMD 9750 x4, 4GB, 2.6.29.2-121.fc11_x86_64), and I experience this problem on every boot.
This the last message printed:
Creating initial device nodes
 
I followed the kernel debugging steps noted in the wiki but with with no success.  
The best I could do is get a stack backtrace for each cpu (sysrq l):
CPU2:
CPU 2:
Modules linked in:
....
RIP: ... native_safe_halt+0xb/0xd
....
Call Trace:
   ... ? default_idle+0x51/0x7c
   ....? c1e_idle+0x124/0x12b
   ....? cpu_idle+0x68/0xb3
   ....? start_secondary+0x199/0x19e

NOTE: This system was previously running f10 and a 2.6.29-rc kernel.

Comment 6 Jimmy Rentz 2009-05-03 05:09:23 UTC 
I was able to get the serial console to work so I attached these sysrq dumps.  Though, I could never capture the boot log...It always resulted in garbage no matter what baud-rate I tried.
Comment 7 Jimmy Rentz 2009-05-05 01:01:33 UTC 
Okay, my problem doesn't look kernel related...There is some problem in mkinitrd.  I installed the version from F10 and rebuilt the initrd and it booted fine.  Will file there.

Possibly the same as bug 499057 which is marked closed but may not actually be fixed.
Comment 9 Bug Zapper 2009-06-09 11:41:21 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

Comment 10 Sander Hoentjen 2009-07-13 15:25:19 UTC 
Whatever it was it seems fixed now.
