Diagnose instruction 0x288 was called to deactivate the diag288 watchdog.
The diagnose call returned an error that cannot be handled by the device driver.
The watchdog stays active and a watchdog timeout will trigger the configured timeout action.
The diag288 watchdog device driver might intentionally be configured to prevent deactivation.
User response
You can configure the diag288 watchdog device driver such that it can be deactivated.
If the diag288 device driver has been compiled as a separate module, diag288_wdt, reload the module
without specifying the 'nowayout' module parameter.
If the diag288 device driver has been compiled into your kernel,
reboot Linux without specifying the 'diag288.nowayout' kernel parameter'.
