library support, but it failed to detect the needed library, here is
the output

custom build kernel with in-house modules based on centos 6, userspace
process appears triggered kernel bug, full console log below, anyone
has seen similar kernel panic before?

I think it is good idea to add these preferences flags and sorted

script to copy large files between kvm guest or some other user space
program leads to disk i/o or VM activities, users get following soft
