So far no simple solution to solve this. I tried disabling the port in resu= me path before host reset, tried toggling port power before host reset, but nothing helped. So looks like we need to focus on why your Intel xHC at 0000:00:0d.0 is reset in resume, and avoid that. Your log shows you have the XHCI_RESET_ON_RESUME quirk BIT(7) set, which explains the reset. [1.901865] xhci_hcd 0000:00:0d.0: hcc params 0x20007fc1 hci version 0x120 quirks 0x0000000200009890 Intel xHC hosts don't normally have this set. Looks like its forced in kern= el cmdline at boot in your case: Kernel command line: ... xhci_hcd.quirks=3D0x80 rw quiet splash Any idea why this is set?=20 Can you try to remove it and see if it works --=20 You may reply to this email to add a comment.
