Hi,
1. I am testing my watchdog driver. The driver uses the internal watchdog (Internal to SOC). 2. I use a single core SOC. 3. I have a workqueue which pets the watchdog every 60 seconds. 4. I trigger a kernel crash by doing a echo c > /proc/sysrq-trigger to trigger a kernel crash 5. Even after the crash, I observe that the workqueue gets periodically executed. (I have a printk inside the workqueue before the pet as a result the watchdog does not reset the board.
My Understanding is When a fatal panic happens, The Kernel is in frozen state (no workques or tasks get executed).
Is my understanding correct or am i missing something here.
Thanks,
Regards, Sriram
