Comment 1 John Reiser 2010-12-16 22:12:13 UTC
It looks like firstboot failed graphical mode, then tried console text mode, and then gdm got started in graphical mode.  The problem with lock order was detected at login to graphical mode.  Booting with text console shows:

The same thing happens on every boot, probably because firstboot is still trying.  I see files such as

Comment 4 Adam Williamson 2011-01-11 17:20:12 UTC
firstboot failing to run is quite an important issue, so setting this as high. Is this still happening in current rawhide?

Comment 5 John Reiser 2011-01-11 19:56:37 UTC
Installing a DVD of today's rawhide hits anaconda bug 668855 (assertion failure in lu_modules_load after Next from timezone dialog).  Installation fails, so we cannot test firstboot until 668855 is fixed.

Comment 6 John Reiser 2011-01-18 05:12:36 UTC
The firstboot problem has been separated into Bug #670379.

Comment 7 Luke Hutchison 2011-02-16 00:30:01 UTC
I just updated to the latest F14 update packages (for the first time in a month or so), and on reboot Nouveau failed to start with this same error message. I'm currently posting this from console-mode elinks because X won't start!  I would say this constitutes major breakage since F14 is a shipping version.

Comment 8 Luke Hutchison 2011-02-16 00:59:31 UTC
Funnily enough, I did a yum update again right after I posted the above, and there was a new kernel version that fixed the problem. I must have gotten the nouveau update but not the corresponding kernel update the first time I updated.

There are similar backtraces in bug 728321, bug 727778 (and perhaps bug 703155). Less similar (but perhaps in the same function) are bug 714746 and bug 710564.

Correct me if i'm wrong, but I think the original part of this bug (lockdep complaint) is fixed now?
