Message-ID: <1320734677-1372-1-git-send-email-hayeswang@realtek.com> Date: Tue, 8 Nov 2011 14:44:37 +0800 From: Hayes Wang <hayeswang@...ltek.com> To: <romieu@...zoreil.com> CC: <netdev@...r.kernel.org>, <linux-kernel@...r.kernel.org>, Hayes Wang <hayeswang@...ltek.com> Subject: [PATCH] r8169: increase the delay parameter of pm_schedule_suspend The link down would occur when reseting PHY. And it would take about 2 ~ 5 seconds from link down to link up. If the delay of pm_schedule_suspend is not long enough, the device would enter runtime_suspend before link up. After link up, the device would wake up and reset PHY again. Then, you would find the driver keep in a loop of runtime_suspend and rumtime_resume.
