Hi Santosh,
Looks like commit 1f5e9c3bc47f ("softirq: fix tasklet_kill() and
its users") causes pandaboard es to not get any IP address on the
smsc95xx USB Ethernet.
Reverting the commits fixes the issue. Any ideas?
Regards,
Tony

Yep. It was discussed today morning and Stephen was suppose to
revert that commit from next for now.
The tasklet core fix even though fixes the issue, there are many
bad users of tasklet which are using tasklet APIs without
doing any sort of tasklet initialization. So there is more
work to do before the tasklet core can be fixed.
