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 <bryanpaluch@xxxxxxxxx> Acked-by: Alan Stern <stern@xxxxxxxxxxxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/usb/host/ohci-hcd.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- 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" Patches currently in stable-queue which might be from bryanpaluch@xxxxxxxxx are queue-4.4/usb-increase-ohci-watchdog-delay-to-275-msec.patch -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
