Date: Mon, 15 Jan 2007 16:37:05 -0200 From: Mauro Carvalho Chehab <mchehab@...radead.org> To: LKML <linux-kernel@...r.kernel.org> Cc: V4L-DVB Maintainers <v4l-dvb-maintainer@...uxtv.org>, Robert Hancock <hancockr@...w.ca>, Mauro Carvalho Chehab <mchehab@...radead.org> Subject: [PATCH 3/9] V4L/DVB (5021): Cx88xx: Fix lockup on suspend From: Robert Hancock <hancockr@...w.ca> Suspending with the cx88xx module loaded causes the system to lock up because the cx88_audio_thread kthread was missing a try_to_freeze() call, which caused it to go into a tight loop and result in softlockup when suspending. Fix that.
