Hi Keir,

Thank you for reply.

If you are running in PAE mode then you should try modifying the kernel file
drivers/net/tg3.c and changing any '#ifdef CONFIG_HIGHMEM' to '#if 0'. It
may also be worth doing some tracing around the code that does
pci_set_dma_mask() to see what path you are taking there and what mask the
driver is choosing to set.

However, the same problem happens to another NIC connected with the same machine. It is the following NIC. 05:03.0 Intel Corporation 82545GM Gigabit Ethernet Controller (rev 04) '# ifdef CONFIG_HIGHMEM' was not being at least defined by the e1000 driver. When pethX was captured with tcpdump, FTP data was not broken. But, when it was captured in the FTP client(other PC), FTP data was broken.

When we create other domain, FTP data seems to be sent again.
Do you have any idea for investigating.

Best regards,

Takanori Kasai
