On a fresh wheezy install I got a flood (~ 50 kHz) of messages of the following

previous, non-Xen boot instead of the expected boot messages and login
prompt.
Workaround (successfully tested): blacklist nouveau in /etc/modprobe.d/.

In a Xen boot the /proc/kmsg buffer fills up before imklog starts so I only
see the PFIFO_CACHE_ERROR messages.

Version: 3.4.1-1~experimental.1+rm
Debian 6.0 Long Term Support has now ended, and the 'linux-2.6' source
package will no longer be updated. This bug is being closed on the
assumption that it does not affect the kernel versions in newer Debian
releases.
If you can still reproduce this bug in a newer release, please reopen
the bug report and reassign it to 'src:linux' and the affected version
of the package. You can find the package version for the running
kernel by running:
uname -v
or the versions of all installed kernel packages by running:
dpkg -l 'linux-image-[34]*' | grep ^.i
and looking at the third column.
I apologise that we weren't able to provide a specific resolution for
this bug.
Ben.
