Saw on almost all the servers range from x64, ppc64 and s390x with kernel 3.9-rc5 and xfsprogs-3.1.10. Never caught this in 3.9-rc4, so looks like something new broke this. Log is here with sysrq debug info. http://people.redhat.com/qcai/stable/log CAI Qian _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
