FreeBSD 8.1-RELEASE-p1 i386 xennet_get_responses messages in console

[Yuriy Kohut]

Hi,

Dom0 details:
CentOS release 5.4 (Final) x86_64
kernel: 2.6.18-164.6.1.el5xen
Xen 3.0.3 (package from RHEL5 build xen-3.0.3-94.el5_4.2)

DomU details:
FreeBSD 8.1-RELEASE-p1 i386
Build from CVS tag: RELANG_8_1

I saw the messages any ones, and they gone after I reinstalled DomU.
I'll try the patch if the issue appears ones more.

Thank you.
