Hi Peter, Since commit 1f874edcb7318 ("usb: chipidea: add runtime power management support") we see the following messages after doing a 'halt' or 'reboot' command: Requesting system halt [ 16.095090] ci_hdrc ci_hdrc.1: remove, state 1 [ 16.100453] usb usb1: USB disconnect, device number 1 [ 16.105558] usb 1-1: USB disconnect, device number 2 [ 16.143356] ci_hdrc ci_hdrc.1: USB bus 1 deregistered [ 16.164063] reboot: System halted Are these remove/disconnect messages normal/expected? Should we adjust the pm_runtime calls inside ci_hdrc_remove()?
