Hi Ian and Keir,

I'm sorry for delaying response.

We tested it with the same machine.
The environment is as follows.

Xen :
- xen-unstable.hg: cs15072
NICs :
- Broadcom Corporation NetXtreme BCM5715 Gigabit Ethernet (rev a3)
- Intel Corporation 82545GM Gigabit Ethenet Controller (rev 04)
Guests :
- DomU
- DomVTi(RHEL5GA)
- DomVTi(RHEL5GA) + PV_ON_HVM(VNIF)
Others:
- SG and TSO flag: ENABLE
- Memory
   ・Domain0       : 1GByte
   ・Guest Domains : 2GByte

The test result was not reproduced as follows.

                           |    Broadcom   |    Intel
----------------------------+---------------+---------------
 DomU                      |   Not broken  |   Not broken
 DomVTi(RHEL5GA)           |   Not broken  |   Not broken
 DomVTi(RHEL5GA)+VNIF      |   Not broken  |   Not broken

Next, the tg3 driver and the e1000 driver were replaced with RHEL5GA.
However, the result was not reproduced similarly.

Is there a correction related to this problem since xen3.0.3?

Best Regards,
