kernel 5.5 kernel and tg3 driver

Hello Experts,
I was using click-1.6.0 on centos 5.3 kernel and recently* ported that to
centos5.5 kernel.*.
After porting, am getting the (*low stack detected by irq handler) and the
*following errors on the console frequently and causing the system
unresponsive totally.
Even after reboot, this issue is re-occurring some time after every 3 days.
System info:
kernel: centos 5.5 (2.6.194-el5)
kernel Modules using: click router
NIC driver: tg3 (broadcom)
Note: The above setup was working successfully for years earlier.
I suspect tg3 driver is doing something here but not sure of how to confirm
this.
Am looking for pointers to start with so that I can investigate. I tried to
do web search on this but not useful.
Also, would like to know any ways/tools to debug using the addresses given
in the stack trace.
Thanks in advance.
