Also, when reporting kernel bugs: *) Whether or not the system is virtualized (and if so, by which VM system) is extremely relevant *) Please report O/S vendor and version *) Consider listing loaded kernel modules. Exotic storage and network drivers are especially interesting (say, fiber channel HBA or TCP offload). *) Research similar reports both internally within the archives and in general. If anything is found supply it as context with the report *) It's helpful to rule out hardware problems. If it's possible to do so, run some hardware diagnostics check out this thread and see if it applies (via google search, warn_slowpath_common tainted) https://www.centos.org/forums/viewtopic.php?t=3642 merlin
