Hi Mingliang, I believe what you're seeing in the dmesg output is related to the kernel module failing, it appears to be a backtrace. I'm fairly sure that PVFS 2.8.2 won't compile cleanly against a 2.6.35 kernel. I imagine you saw some warnings during the make kmod although the build may have "succeeded". The latest release of OrangeFS may work although I'm not certain. It will work with kernels up to 2.6.34 and support for newer kernels is in the works.
If you can post the output from your make kmod I can tell you for sure but I would recommend getting the latest OrangeFS release and posting that output. I can work on getting the necessary changes into our development branch for you to use.
