Subject: b44 needs to reclaim its interrupt after swsusp
Date: Wed, 21 Apr 2004 02:02:08 +0200 [thread overview]
Message-ID: <20040421000208.GA3160@elf.ucw.cz> (raw)
Hi!
b44 needs to free/reclaim its interrupt across suspend in order to
work. This patch makes it work, but I'm not quite sure why its
needed. Interrupt is listed as IO-APIC-level in /proc/interupts.
