Xavier NX hardware pcie connect pcie switch pm8561 problem

Hi
We use the Xavier NX root complex connnect the pcie switch pm8561 upstream and a ssd connect pcie pm8561 downstream, but Xavier NX upstream errors happended and ssd downstream is good 。 We think there have some compatibility problem? Or some paramers is wrong? We need helppcie_log.txt (77.5 KB)

I see the following error in the log.
[ 3.043053] pcieport 0005:00:00.0: [ 5] Surprise Down Error (First)
Could you please change nvidia,max-speed = <4>; to nvidia,max-speed = <1>; and try once?
Has this switch been verified with any other platform?
