upgraded from 2.6.35.7 to 2.6.36 => panics
so then upgraded from 2.6.36 to 2.6.36.2 => same panic() while dd
As I said this happens equally if I connect my backup station to either
native USB 2.0 (USB3.0 NOT plugged in!) or the conceptronics USB 3.0.
The backup station is Sharkoon SATA Quickport 3.0.
Hope this helps.
