CentOS - May 2008 - eth1 changed to __tmp78668633 in recent kernels

Hi list,

kernel-xen-2.6.18-53.1.14.el5 and 
kernel-xen-2.6.18-53.1.19.el5 
do not detect/initialize/whatever my eth1 network card any more. 

With 
kernel-xen-2.6.18-53.1.13.el5 
everything is working as expected. 

With the two recent kernels I only get an Interface named __tmp786686833
which is not added to xenbr...

lspci -v to the adapter in question says

02:00.0 Ethernet controller: Intel Corporation 82572EI Gigabit Ethernet
Controller (Copper) (rev 06)
        Subsystem: Intel Corporation PRO/1000 PT Desktop Adapter
        Flags: bus master, fast devsel, latency 0, IRQ 17
        Memory at febe0000 (32-bit, non-prefetchable) [size=128K]
        Memory at febc0000 (32-bit, non-prefetchable) [size=128K]
        I/O ports at ec00 [size=32]
        Expansion ROM at feba0000 [disabled] [size=128K]
        Capabilities: [c8] Power Management version 2
        Capabilities: [d0] Message Signalled Interrupts: 64bit+
Queue=0/0 Enable-
        Capabilities: [e0] Express Endpoint IRQ 0

ip link says

2: __tmp786686833: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000
    link/ether 00:1b:21:0e:a9:3b brd ff:ff:ff:ff:ff:ff

In modprobe.conf I have 
alias eth1 e1000
for the adapter in question. The module itself is loaded.



Any Ideas how to fix this?

cheers 
Henry

Update: Thanks to Christopher Isip from the xen-list. I found a solution
for the problem. Disabling xend at runlevel 2. With this configuration
every kernel works as expected. With xend enabled at runlevel 2 only the
older kernel works as expected. 

Is this intended - did I miss something?
