Fatal error loading floppy module
Last modified: 2009-11-04 18:36:35 EST
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.)
Steps to Reproduce:
1. Boot from installation DVD or initiate NFS installation
Anaconda does not seem to proceed to stage2.
Anaconda installation process should continue normally.
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/126.96.36.199-167.fc11.x86_64/kernel/drivers/block/floppy.ko.gz): 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.
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.
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.)
