Ian from the trace below I don't see an error related to PF_RING but a soft-lockup (see below).
I have tested PF_RING on 2.6.24 and .26 and have not experienced the problem you reported.
hmm... I have restarted the operating system with CentOS's original kernel and done again my experiments. I found that bug has not occurred again.
I don't know why. Maybe, the traditional libpcap has no provided enough capability like PF_RING. Or, perhapse something wrong is indeed in patched kernel or Dell hardware drivers.
BTW, could you tell me what OS distribution you used in your testing PF_RING, RedHat AS4 or Others? And what kernel source codes are downloaded, from vendor's websites or www.kernel.org?
I very thank you if you can recommend what OS distribution and what kernel version are put together can achieve the maximal stability.
Thank anybody!
Ian
If you need a newer kernel to use that patch, I would recommend something that runs more cutting edge for that server, maybe Gentoo or Fedora 9. I don't recommend patching CentOS with a new kernel as you lose the main benefit for using an Enterprise distro .. stability. I love CentOS, but no one distribution can be everything for everyone. That is why there are so many choices.
