[ELDK] facing possible kernel preemption

[Dipanjan Dutta]

Hello All,

 

I have a module which I inserted into 2.6.16 kernel (ELDK 4.1).

 

After a while, I see the module not responding and see traces like:

(my module name is sa_inop)

...

scheduling while atomic: sa_inop/0x00000101/311

ssIsr: vectNum = 33

Any idea, what could be the issue? I have a watchdog timer in the system
and whenever such print comes, the watchdog goes for a reboot.

 

Thanks,
