ChangeSet 1.1579, 2005/03/16 09:22:37-03:00, [email protected] [PATCH] Fix softdog no reboot on unexpected close There is a bug in the softdog.c (v 0.05) in the 2.4 kernel series (certainly in 2.4.29 and there are no references to it in the latest Changelog) that won't reboot the machine if /dev/watchdog is closed unexpectedly and nowayout is not set. The softdog.c (v 0.07) in 2.6.11 is not affected, but I have been informed by the vendor of analog output cards that we use (ICP DAS) that they currently have no plans to port their driver to the 2.6 series. Anyway, here is a simple patch that does the job. softdog.c | 2 +- 1 files changed, 1 insertion(+), 1 deletion(-) diff -Nru a/drivers/char/softdog.c b/drivers/char/softdog.c --- a/drivers/char/softdog.c 2005-03-16 15:02:41 -08:00 +++ b/drivers/char/softdog.c 2005-03-16 15:02:41 -08:00 @@ -124,7 +124,7 @@ * Shut off the timer. * Lock it in if it's a module and we set nowayout */ - if (expect_close || nowayout == 0) { + if (expect_close && nowayout == 0) { del_timer(&watchdog_ticktock); } else { printk(KERN_CRIT "SOFTDOG: WDT device closed unexpectedly.
