[ Upstream commit 4e36c0f20cb1c74c7bd7ea31ba432c1c4a989031 ]
When probing, the hardware is not brought into a known state. This may
be a problem when a hypervisor restarts Linux without resetting the
hardware, leaving an old state running. Make sure the hardware gets
initialized, especially interrupts should be cleared and disabled.
