This happens on both my Fedora 18 and Fedora 17 partitions when mounting filesystems from very old servers that need the proto=udp option to talk. The redhat bugzilla is here: https://bugzilla.redhat.com/show_bug.cgi?id=908451 There is a photo of the walkback in that bugzilla: svc_delete_xprt+0x12a svc_recv+0x101 ? nfs_callback_authenticate+0x50 nfs4_callback_svc+0x3b kthread+0xc0 ? ftrace_raw_event_xen_mmu_flush_tlb_others+0x50 ? kthread_create_on_node+0x120 ret_from_fork+0x7c ? kthread_create_on_node+0x120
