The hardware doesn't support s3, only s2idle. > @davidhubbard isolated iGPU memory allocation as a variable: That's really odd to me to change things. Are you 100% sure? This issue feels like a race condition of some sort, especially if you can unbind and rebind after the issue happens to recover. > The RESET_ON_RESUME quirk may possibly work as bandaid, try > xhci_hcd.quirks=3D0x80 boot parameter or pass it to xhci_hcd module if us= ing > one. All USB devices will be dropped and re-enumerated on resume. This doesn't seem ideal to me if most suspends are fine. Until we get to t= he bottom of this maybe we want a RESET_ON_FAILURE type of behavior instead to= use in the resume routine? --=20 You may reply to this email to add a comment.
