Have just updated a Fedora 9 system from 2.6.25.4-30.fc9.x86_64 to 2.6.25.6-55.fc9.x86_64 and resyncs on an md RAID6 array containing an XFS filesystem now generates these messages for the duration of the resync. Resyncs on previous kernel did not cause this. INFO: task xfssyncd:30716 blocked for more than 120 seconds.
