>Description:

On a ThinkPad T40, all USB ports are dead after resuming from ACPI
S3 suspend.

USB ports are probed like this:

uhci0: <Intel 82801DB (ICH4) USB controller USB-A> port 0x1800-0x181f irq 3 at device 29.0 on pci0
usb0: <Intel 82801DB (ICH4) USB controller USB-A> on uhci0
usb0: USB revision 1.0
uhub0: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered
uhci1: <Intel 82801DB (ICH4) USB controller USB-B> port 0x1820-0x183f irq 6 at device 29.1 on pci0
usb1: <Intel 82801DB (ICH4) USB controller USB-B> on uhci1
usb1: USB revision 1.0
uhub1: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub1: 2 ports with 2 removable, self powered
uhci2: <Intel 82801DB (ICH4) USB controller USB-C> port 0x1840-0x185f irq 5 at device 29.2 on pci0
usb2: <Intel 82801DB (ICH4) USB controller USB-C> on uhci2
usb2: USB revision 1.0
uhub2: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub2: 2 ports with 2 removable, self powered
ehci0: <EHCI (generic) USB 2.0 controller> mem 0xc0000000-0xc00003ff irq 11 at device 29.7 on pci0
ehci_pci_attach: companion usb0
ehci_pci_attach: companion usb1
ehci_pci_attach: companion usb2
usb3: EHCI version 1.0
usb3: companion controllers, 2 ports each: usb0 usb1 usb2
usb3: <EHCI (generic) USB 2.0 controller> on ehci0
usb3: USB revision 2.0
uhub3: (0x8086) EHCI root hub, class 9/0, rev 2.00/1.00, addr 1
uhub3: 6 ports with 6 removable, self powered

When resuming, I get these errors:

usb0: cannot start
usb1: cannot start
usb2: cannot start
usb2: host system error
usb2: host controller process error
usb2: host controller halted
uhub0: port 1 reset failed
uhub0: illegal enable change, port 2
uhub1: port 1 reset failed
uhub1: illegal enable change, port 2
uhub2: port 1 reset failed
uhub0: port 2 reset failed
uhub0: illegal enable change, port 1
uhub1: port 2 reset failed
uhub1: illegal enable change, port 1
uhub0: port 1 reset failed
uhub0: illegal enable change, port 2
uhub1: port 1 reset failed
uhub1: illegal enable change, port 2
uhub0: port 2 reset failed
uhub0: illegal enable change, port 1
uhub1: port 2 reset failed
uhub1: illegal enable change, port 1
uhub0: port 1 reset failed
uhub0: illegal enable change, port 2
uhub1: port 1 reset failed
uhub1: illegal enable change, port 2

(These last messages loop forever...).

It might be DSDT related, the ASL file I use can be found at

>How-To-Repeat:

Enter S3 state on a ThinkPad T40 and resume again.
