From ed6d6f8f42d7302f6f9b6245f34927ec20d26c12 Mon Sep 17 00:00:00 2001 From: Bryan Paluch Date: Mon, 17 Oct 2016 08:54:46 -0400 Subject: [PATCH] usb: increase ohci watchdog delay to 275 msec Increase ohci watchout delay to 275 ms. Previous delay was 250 ms with 20 ms of slack, after removing slack time some ohci controllers don't respond in time. Logs from systems with controllers that have the issue would show "HcDoneHead not written back; disabled" Signed-off-by: Bryan Paluch Acked-by: Alan Stern Cc: stable Signed-off-by: Greg Kroah-Hartman --- drivers/usb/host/ohci-hcd.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/usb/host/ohci-hcd.c b/drivers/usb/host/ohci-hcd.c index 1700908b84ef..86612ac3fda2 100644 --- a/drivers/usb/host/ohci-hcd.c +++ b/drivers/usb/host/ohci-hcd.c @@ -72,7 +72,7 @@ static const char hcd_name [] = "ohci_hcd"; #define STATECHANGE_DELAY msecs_to_jiffies(300) -#define IO_WATCHDOG_DELAY msecs_to_jiffies(250) +#define IO_WATCHDOG_DELAY msecs_to_jiffies(275) #include "ohci.h" #include "pci-quirks.h" -- 2.20.1
