User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.5) Gecko/20091103 SUSE/3.5.5-2.1 Firefox/3.5.5 On our server while running nightly backups, the mptscsih driver throws many errors and the load on the server goes up to about 240, and the server gets almost unresponsive. Only a reboot helps. This backups have been running fine on the same hardware for over a year. The server is running openSuSE 11.1 with kernel-default-2.6.27.37-0.1.1. Reproducible: Always Steps to Reproduce: 1a. let the nightly backup, dirvish (www.dirvish.org), which uses rsync to backup, and heavily uses hard links to previous backups. It will hang. 1b. starting the same rsync command on the console also triggered similar errors, see 3rd attachment. Actual Results: The server get very high load. IO hangs. rsync gets into D state and cannot be killed. Expected Results: backup/rsync should run without errors.
