Subject: [I4L] Fix IRQ-sharing lockup in nj_s
Date: Tue, 27 Jul 2004 18:22:41 +1000 [thread overview]

Hi:
This is a backport of a fix that's already in 2.6. The problem is that
nj_s is enabling interrupts before the handler is even installed. This
patch delays the call until after the handler has been registered.
Cheers,
