    SubjectRe: [patch 2.6.13-rc6] watchdog: fix oops in softdog driver
    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 <>
    > 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.

    I'll add this to the watchdog tree.
