Hi Gokul,
When you power off the card via the i2c, it forcefully power off the 
card without notify the kernel? That is, during the card power off 
sequence it manages to send a last AER isr to report the error and die? 
I am kind of expect the pcie surprise removal or hot plug driver will 
handle it correctly.

Thanks,
Thomas
