Hello sameerarvikar,

According to your boot log, it seems that you are using Linux Kernel SDK 1.9 pre-built Linux Kernel. I didn't find this problem on P2041ARDB target board.

Did you modify the dts file? If yes, would you please also provide it? Probably there is problem in the dts file.

What kind of PCIe device did you use on your target board?

Have a great day,
TIC
