As the usb list is still in Cc: - Artem's lcpci dump shows that his machine features XHCI controllers. Can anyone think of a relation to this problem?

And Artem, is there any way you boot your system on an older machine that only has EHCI ports? Thinking about it, I wonder whether the freeze in VBox and the crashes on native hardware have the same root cause. In that case, would it be possible to share that VBox image?

Don't grasp at straws. All of the kernel logs Artem has posted show ehci-hcd; none of them show xhci-hcd. Therefore the xHCI controller is highly unlikely to be involved.

You might be right - I'm just looking for differences between his setup and mine that would explain why nobody else sees a severe bug that is 100% reproducible for him.
