hi, all

RHEL 5.4 is the host os, and kernel-xen.x86_64.2.6.18-164.el5,
kernel-xen-devel.x86_64.2.6.18-164.el5 and xen-libs.3.0.3-94.el5  are
installed.
After that, the grub file is :

title Red Hat Enterprise Linux Server (2.6.18-164.el5xen)
        root (hd1,0)
        kernel /xen.gz-2.6.18-164.el5
        module /vmlinuz-2.6.18-164.el5xen ro
root=/dev/VolGroup00/LogVol00 rhgb quiet
        module /initrd-2.6.18-164.el5xen.img

In this edition, everything is ok. The system runs as normal and the
network runs normally too.
However, when I clone xen-4.0.0-rc1 and compile it (make xen;make
install-xen) and configure it in grub as :
title xen-4.0.0-rc1 (2.6.18-164.el5xen)
        root (hd1,0)
        kernel /xen-4.0.0-rc1.gz
        module /vmlinuz-2.6.18-164.el5xen ro
root=/dev/VolGroup00/LogVol00 rhgb quiet
        module /initrd-2.6.18-164.el5xen.img

When I boot it, I found in the dmesg like this and the network can't
be used after that:

IRQ handler type mismatch for IRQ 274

Does anybody know how to solve this problem?
Thanks very much!
