Regarding kernel work queue issues

[Raj Kumar]

Hi,
 
I have developed a device driver which is using default kernel work queue thread for deferring tasks. This work queue thread
while executing exits sometimes in function calls. It exits sometimes at one point and sometimes at another point without any panic. so the next time when the work is scheduled, it works normally.
 
can this problem be due to stack limit? 
 
Regards
Raj
