[ Upstream commit a81bcfb6ac20cdd2e8dec3da14c8bbe1d18f6321 ]
When high load on the DWC3 SuperSpeed port, the controller crashes with: [ 221.141621] xhci-hcd xhci-hcd.0.auto: xHCI host not responding to stop endpoint command. [ 221.157631] xhci-hcd xhci-hcd.0.auto: Host halt failed, -110 [ 221.157635] xhci-hcd xhci-hcd.0.auto: xHCI host controller not responding, assume dead [ 221.159901] xhci-hcd xhci-hcd.0.auto: xHCI host not responding to stop endpoint command. [ 221.159961] hub 2-1.1:1.0: hub_ext_port_status failed (err = -22) [ 221.160076] xhci-hcd xhci-hcd.0.auto: HC died; cleaning up [ 221.165946] usb 2-1.1-port1: cannot reset (err = -22)
Setting the parkmode_disable_ss_quirk quirk fixes the issue.
