Description Wendy Hung 2003-12-16 09:56:50 EST
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; 

Description of problem:
After the Red Hat 2.1 AS QU3 installation on a Bladecenter was 
completed, the following text was displayed on the screen.
The blade never rebooted on its own after the install.

Ummouting filesystem....
/mnt/runtime done
disabling /dev/loopo
/proc/bus/usb done
/proc done
/dev/pts dome
/mnt/sysimage/boot done
/mnt//sysimage/proc/bus/usb done
/mnt/sysimage done 

Apparently this occurs while any USB based filesystems are mounted; 
an endless loop waiting for the filesystem to respond to the unmount 

Unable to reproduce with RHL 9.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install AS 2.1 Update 3 on system using USB CDROM such as 

Actual Results:  Requires manual hardware reset.

Expected Results:  System reboots.

At that point, everything looks unmounted -- /mnt/source should be the
last one that gets unmounted.  Did this happen with U2?  What are the
USB filesystems being mounted for?
Comment 2 Wendy Hung 2003-12-16 16:33:54 EST
Yes this was reproduced with U2.  The USB CD-ROM is mounted for the 
installation and does appear to be unmounted.  However, the system 
does not reboot.
Comment 3 Jeremy Katz 2003-12-16 16:36:14 EST
Can you switch ttys at this point?  If so, is there anything odd on
tty4?  Can you get the output of Alt+SysRq+T?
Comment 4 Wendy Hung 2003-12-17 16:54:21 EST
Looks like it's not an anaconda bug since a similar hang can be 
reproduced post-install.

1.  Mount USB CD-ROM
2.  Attempt to reboot by executing init 6
3.  Server will stop at "Unmounting filesystems" message.

Manual reset of the server is required.

ok not a regression "just" a normal bug
Comment 6 Wendy Hung 2004-01-07 13:51:50 EST
Has anyone at Red Hat been able to reproduce this on a blade?
I did find a possible workaround:

At the end of the installtion, at the "Finished" screen, I switched 
to tty2 and ran "umount /mnt/source".  I switched back to the GUI 
screen, and clicked "Finished".  System did not reboot and last 
message seen was "Ejecting /tmp/cdrom"

I reinstalled and this time I ran these commands at the "Finished" 
umount /mnt/source
rm /tmp/cdrom

System did reboot, but CD was left in the CDROM.
