Hi Chuck, > The softdog watchdog timer has a bug that can create an oops: > > 1. Load the module without the nowayout option. > 2. Open the driver and close it without writing 'V' before close. > 3. Unload the module. The timer will continue to run... > 4. Oops happens when timer fires. > > Reported Sun, 10 Oct 2004, by Michael Schierl <[EMAIL PROTECTED]> > > Fix is easy: always take a reference on the module on open. > Release it only when the device is closed and no timer is running. > Tested on 2.6.13-rc6 using the soft_noboot option. While the > timer is running and the device is closed, the module use count > stays at 1. After the timer fires, it drops to 0. Repeatedly > opening and closing the driver caused no problems. Please apply.
