== Precise SRU Justification ==

A bug in the upstream ite_cir driver has been triggered recently on Precise
kernels, causing some systems (in particular Dell XPS 1340) to crash during

The problem is related to an early registration of an ISR during the device
probe process.  This caused IRQs to be served before the driver initialisation
had been completed.

== Fix ==

Moving the invocation of request_irq() later in the probe solved the problem.

== Impact ==

There are several users reporting the crash in their system while booting with
recent Precise kernels.

== Test Case ==

Just booting triggers the problem.
