-Subject: [PATCH] xhci: Keep interrupt disabled in initialization until host is
- running.
-
-irq is disabled in xhci_quiesce(called by xhci_halt, with bit:2 cleared
-in USBCMD register), but xhci_run(called by usb_add_hcd) re-enable it.
-It's possible that you will receive thousands of interrupt requests
-after initialization for 2.0 roothub. And you will get a lot of
-warning like, "xHCI dying, ignoring interrupt. Shouldn't IRQs be
-disabled?". This amount of interrupt requests will cause the entire
-system to freeze.
-This problem was first found on a device with ASM2142 host controller
-on it.
