Hi,

Could you please read the device control register by using command below?

sudo setpci -d 8086:094C 0x78.L

This is to check if bit 7:5 is set to 001b for 256 bytes max payload size? If not, please configure the bit 7:5 as 001b, and then run the test again.

For example:

sudo setpci -d 8086:094C 0x78.L=0009203e (please change bit 7:5 as 001, the rest remain the same as what you read out)

If above do not help, please also read the uncorrectable & correctable status register to further understanding the problem.

sudo setpci -d 8086:094C 0x110.L

sudo setpci -d 8086:094C 0x104.L

Regards -SK
