Re: [Xen-devel] Data broken during FTP test

["Kasai Takanori" <kasai.takanori@xxxxxxxxxxxxxx>]

Hi All,

We are investigating the problem that data was broken during FTP test.

This problem seems not to be reproduced since changeset 13511 of 
xen-unstable.hg.
Moreover, it is generated only by PAE of X86.
(It did not reproduce it when working with x86_64 in the same machine.)
When HIGHMEM was not used, it didn't reproduce it.

The kernel has been updated from 2.6.17 to 2.6.18 by this changeset.
Because the amount of the correction is large,
we do not understand where of this change set this problem is corrected.

Will you understand where to be corrected?
If the part where this problem is corrected can be understood,
could you teach to us?


The environment for your information reproduced is as follows.

Xen :
- xen-unstable.hg: before cs13511
NICs :
- Broadcom Corporation NetXtreme BCM5715 Gigabit Ethernet (rev a3)
- Intel Corporation 82545GM Gigabit Ethenet Controller (rev 04)
Guests :
- DomU
- DomVTx(RHEL5GA)
- DomVTx(RHEL5GA) + PV_ON_HVM(VNIF)
Others:
- SG and TSO flag: ENABLE
- Memory
  ・Domain0       : HIGHMEM
  ・Guest Domains : 2GByte

Best Regards,
