User-Agent: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.7.3)
Description of problem:
After a successful installation of FC3, if you execute a reboot
command manually, kernel panics.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot through the Installation CD1
2. Select some kind of build (to demonstrate this problem, "minimal
system" installation type is good enough)
3. Wait for the installation to complete, and when it advises that the
installation is over and asks you press "Reboot" button, do not press
that button. Instead change to virtual console 2 (ctrl+alt+f2)
4. Type in "reboot" (to initiate a manual reboot for example. In my
case it is a old habit of rebooting a machine manually :)
Actual Results: Kernel panics
Expected Results: Kernel may not panic, of course :)
The panic message is:
The system is going down NOW!!
Sending SIGTERM to all processes.
Kernel panic - not syncing: VFS: Unable to mount root fs on
I suspect that the installer unmounted root fs when it presented the
reboot option in the GUI. Perhaps it should do that after the user
asks to reboot.
[Alternatively, before preseting the reboot option in the GUI, the
installer may terminate all the console sessions (including the shell
at the virtual terminal 2). It that is a no-no then Installer may not
allow the user to access any other virtual terminals at that time or
have no reboot command at all or advise it is not allowed etc.]
Fixed in CVS. Calling /sbin/reboot instead of just reboot will
