Description Ryan Fonnesbeck 2009-06-17 19:16:26 EDT
Description of problem:
Trying to install Fedora 11 on IBM HS21 BladeServer.  DVD, NFS, and NFS+Kickstart installations all exhibit same behaviour where anaconda does not seem to proceed to stage2.  After initial kernel messages, the screen goes black.

There is a fatal error message on vt/3 when the floppy kernel module tries to load.  (There is no floppy device on this system.)

How reproducible:

Steps to Reproduce:
1.  Boot from installation DVD or initiate NFS installation
Actual results:
Anaconda does not seem to proceed to stage2.

Expected results:
Anaconda installation process should continue normally.

Additional info:

Initial kernel boot messaging displays normally.  After screen goes black, virtual terminals are no longer available.

Final messages before fading to black:

FATAL: Error inserting floppy (/lib/modules/ No such device

Anaconda will proceed to stage 2 if the "noprobe" option is passed, but bug #499425 prevents NFS installation from proceeding.

floppy.ko is one of the modules we unconditionally load, as it may be needed for a variety of update possibilities.
Comment 2 Peter McNabb 2009-07-28 13:51:43 EDT
It looks like the HS21 BladeServers require a "nomodeset" option to the kernel (for installation and afterwards). I was seeing similar behavior and after trial and error found that option to work.

The floppy error was a red herring.
Comment 3 Ryan Fonnesbeck 2009-07-28 17:36:49 EDT
I can confirm that this was, in fact, a display issue; and not an issue with the floppy module.  Passing the "nomodeset" option remedies the problem.

(Though I still think that reporting "FATAL" errors for non-fatal events warrants a bug report.)
