Subject: two warns on slowpath

Hi,

Since loading netconsole a couple of days ago on the two machines of a
heartbeat cluster hosting Xen virtual machines, I got the attached
warn_on_slowpath messages, one on each.  It never happened before, so
I thought I could as well report them in case it's interesting for
you.  The netconsole module parameter is like

netconsole=@...253.2.8/eth-gb1,6666@...253.2.1/00:09:6b:8c:88:6b

with different port numbers on the two hosts.  The eth-gb[12] physical
interfaces are bonded, but I couldn't run netconsole on bond0, as it
has no netpoll support.  The source IP is on bond0.  There are also
several 802.1q subinterfaces over bond0, which are bridge ports.

The kernel is basically 2.6.26.6 with the SuSE Xen patch for dom0
support (the Debian Lenny kernel).
