Hi Tushar,

Please find eeprom from attachment.

Do you have lspci -vvv dump of entire system before and after issue

occurs? If you have can you send it to me?

quoted

Sorry but I meant the full lspci -vvv of *entire system* before and

after issue occurs and not of 82571 only.

Before:
=======
00:00.0 Host bridge: Intel Corporation 5500 I/O Hub to ESI Port (rev 22)
Subsystem: Oracle Corporation Device 5352

Joe, thanks for all the data.
You said you have changed max payload size and issue stop occurring. How did you change it? Where did you make that change in BIOS or EEPROM or in PCIe config space?
Also please send me the full dmesg of entire system after you change max payload size.

Thanks.
