Public bug reported:
The USB3 port of my Samsung Series 9 notebook (NP900X3D) does not work
after a suspend/resume cycle. The other USB2 ports work fine.
This problem has appeared between kernel 4.13.0-45-generic (works
flawlessly) and 4.15.0-24-generic (fails every time). IIUC there has
been a big refactoring of the power management code between these two
versions.
Trying to plug a USB stick into the USB3 port after a resume leads to
the following error being logged in dmesg:
[ 345.034905] usb usb2: root hub lost power or was reset
[ 345.034912] usb usb3: root hub lost power or was reset
[ 345.094619] xhci_hcd 0000:03:00.0: Host took too long to start, waited
16000 microseconds.
[ 345.094643] xhci_hcd 0000:03:00.0: PCI post-resume error -19!
[ 345.094646] xhci_hcd 0000:03:00.0: HC died; cleaning up
[ 345.094651] xhci_hcd 0000:03:00.0: HC died; cleaning up
After this error the USB3 port will not work until the system is
rebooted.
This error is shown only the first time when a USB device is inserted
after the resume. In all subsequent tries no messagess will be logged to
dmesg.
