I have one issue, at customer machine the user space process is hogging up the processor (soft lockup)along with 2 kernel process and dump stack trace showing RIP at _ticket_spin_lock in all 3 process.
As i know "If an user-space process had caused the soft-lockup, a line identifying the process by its pid would logged, followed by the contents of various CPU-registers without a call-trace of any sorts" but in my case i am getting dump stack trace for user process too.
is it coming from a misbehaving user space app? is it normal functionality of soft lockup? if is it functionality of soft lockup then how to resolve the issue?
Any help will be highly appreciated.
it is x86_64 machine and kernel is 3.1.10. I know all 3 process are waiting for _ticket_spin_lock. see :-

Hi SumitGemini,
Thank you for the post. What is the exact network adapter model you used? Is it onboard NIC or standalone network adapter? What is the exact board or system used here?
Please share the link where you downloaded the igb driver.
Thanks,
wb

Hi SumitGemin,
Can you confirm if you have installed the driver from this link?
https://sourceforge.net/projects/e1000/files/igb%20stable/
Your ethtool output driver version is 3.2.10-k,there is higher versions in the link above.
