xhci_hcd 0000:02:00.0: WARN: Stalled endpoint

Hi,
I'm using Debian Squeeze amd64 with a PCI Express USB3 controller[1], 
unfortunately I get tons of
xhci_hcd 0000:02:00.0: WARN: Stalled endpoint
when I attach my 2.5" external disk and I even got an hard reboot 
(nothing in messages).
Squeeze's kernel is 2.6.32.

Same problem when I detach a simple mouse/keyboard:

Is there any fix to backport? I need USB3 for the backups :(

Thanks,
Niccolò
