Hi
The following message (its one line) is swamping /var/log/messages,
occurring many times per second. Does anyone know what it means, and
especially how to fix it, or at least turn it off. The machine seems to
be running OK. Thanks.

OK, here it is, with some line wrap.

I am using the nvidia driver because I can't get nouveau to bring up the login
screen, but I can get to multiuser and then do a startx. That is better than
megabytes of error messages in log files.
$ modinfo -F filename nouveau
/lib/modules/3.11.0-3.fc20.x86_64/kernel/drivers/gpu/drm/nouveau/nouveau.ko
You can try it with that one,
http://kojipkgs.fedoraproject.org/packages/kernel/3.11.0/3.fc20/x86_64/
kernel-3.11.0-3.fc20.x86_64.rpm
# rpm -ivh kernel-3.11.0-3.fc20.x86_64.rpm
Check&update the BIOS.
$ su -c "dmidecode -t bios"
$ su -c "dmidecode -t baseboard"
If IOMMU still bothers, check whether you can disable it via BIOS.
You can also try to set up pass through mode with the kernel parameter,
EXTLINUX:
/boot/extlinux/extlinux.conf
append … iommu=pt
GRUB:
/boot/grub2/grub.cfg
linux … iommu=pt

The Nvidia related discussion forum is right here:

After reading several articles on the nvidia Optimus and the problems
with having dual hardware, I realized that my machine had dual hardware
also. lspci | grep VGA gives
01:01.0 VGA compatible controller: ASPEED Technology, Inc. ASPEED
Graphics Family (rev 10)
04:00.0 VGA compatible controller: NVIDIA Corporation G92 [GeForce 9800
GT] (rev a2)
I had noticed a considerable delay in booting when it came to the ast
module, so I decided to try and blacklist it. After trying several
different options, I found that putting 'modprobe.ast=blacklist' on the
kernel line succeeded. Booting takes about half the time, and nouveau
now opens the login screen. This doesn't solve the subject directly (I
haven't tried the nvidia driver with the blacklist), but it solves my
problem in that I can now boot all the way into graphical mode
successfully.
