Hi, has anyone had a chance to look at this.

Comment 5 rpecorella 2012-02-02 20:11:42 UTC

Is there a workaround or errata on this problem?  Thanks, Richard

I don't believe this is related to video at all, seems to be networking from the message.  Certainly not nouveau, as with "modeset=0" it's prevented from doing anything.

Reassigning so someone may be able to help!

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Looks like an error message from the libfcoe stack.

Reassigning

Comment 13 Neil Horman 2012-12-06 15:44:37 UTC

This isn't a bug at all, its a informational message.  and one thats only displayed when  the console is in text mode (likely why it only shows up with nouveau.modeset=0), and when libfcoe debugging is enabled.  I imagine the customer has libfcoe.libfcoe_debug_logging set on the command line or in one of the modprobe config files.  remove that and this will go away, not that it hurts anything anyway.
