Hi, I try to use Nouveau for the first time today. Everything seems to work
fine, except that my syslog is flooded with this message :
"kernel: nouveau 0000:01:00.0: Unhandled PFIFO_INTR - 0x00000010"

In the previous 3 hours, this message has been logged ~25000 times.

It seems related with my activity, with an empty desktop and doing nothing, the
message still print but much less often. As soon as I began typing or opening a
menu, the message is logged as much as 50 times per second.

I use DDX, libdrm and DRM snapshots from today. DRM comes from the
master-compat branch (commit         4ea84bc8aeaccc57958b8fb2847965d52b6bda72).
I don't use KMS.
Composite is enabled and used with metacity.

X.Org X Server 1.6.3
Linux 2.6.30.3

My card is :

There are some info missing I think.

It would help if you could dmesg > file.log and attach file.log, attach your
/var/log/Xorg.log. Also tell us if you are trying to use the mesa gallium3d
nouveau driver which because of its incomplete (and unsupported) state are know
to generate this kind of messages.

Xorg.log with correct libglx

Oops, sorry, I didn't see that. Same problem with the correct libglx, here
is
the new Xorg.log.

I had similar messages when vesafb was activated before loading the nouveau
module.

Setting vga=normal on the kernel command line resolved the issue for me.

Can you please test current Nouveau? If the bug still occurs please attach
kernel log from boot to start of the flood.

FIXED. If you can still reproduce it, please reopen.
