Hi,

I suggest you bring this issue up with Dell customer support.

Further, maybe Linux XHCI / EHCI has a quirk for Dell R630.

Alternativly you can try to debug the XHCI/EHCI debug prints on your 
own. If you get a timeout it means something is not communicating like 
expected in the XHCI/EHCI DMA descriptors.
