On SC7180, in host mode, it is observed that stressing out controller results in HC died error:
xhci-hcd.12.auto: xHCI host not responding to stop endpoint command xhci-hcd.12.auto: xHCI host controller not responding, assume dead xhci-hcd.12.auto: HC died; cleaning up
And at this instant only restarting the host mode fixes it. Disable SuperSpeed instances in park mode for SC7180 to mitigate this issue.
Let me please repeat the question from v1:
Just out of curiosity, what is the park mode?
