[Xen-devel] Xen3.1 network freeze with IPMI

[marek cervenka <cervajs@xxxxxxxxxx>]

hi,

i am using supermicro with remote management IPMI 
(http://www.supermicro.com/manuals/other/SUPER_IPMI_2.0.ppt)
IPMI card has own MAC adress and IP address (but ethernet cable is shared)

i am using xen 3.1 from www.xensource.com (on centos5.0)

if IPMI card is "freezed*" (cannot connect to IPMI) then xen3.1 
kernel(NETWORK) works fine
if i do "mc reset cold" from host system then NETWORK freeze (but IPMI 
works)
i can connect with IPMI to the system. dmesg,messages,ifconfig all looks 
ok
but network do not work. /etc/init.d/network restart does not help, i must 
restart whole server
ping from this machine ends with
PING <other ip>  56(84) bytes of data.
> From <server ip> icmp_seq=0 Destination Host Unreachable
this is strange

server without IPMI works fine. server with IPMI without XEN kernel works 
fine. (IPMI does not like XEN and backward)
do you have idea what is the problem?

* IPMI card sometimes freeze and is unreachable. it must be restarted :(
