Hi @Hrithik , Looks like you are using an older version of the driver will check and get back to you on the logs

Hi @Vivek_gunapati ,

Did you find the cause of brcm crash from the logs?

Thanks.

Hi @Hrithik , As i understand that you are porting and upgrading the driver to a newer release. 
Could you please let us know if the driver crashes with the newer release as well?

Regards
Vivek.
