We have some similar HW here and we suspect either CPU or Northbridge too, we where seeing day to day panics and a scrub would pretty much guarantee a panic. We also replaced the CPU's with no joy but found disabling the cores of the CPU in the second socket made the issues go away so strengthening the Northbridge theory. Try disabling the cores with the following and see if it helps:- /boot/loader.conf hint.lapic.1.disabled="1" hint.lapic.2.disabled="1" Unfortunately if you have perceived corruption due to this type of issue there's no guaranteeing what state your data is really in :( Regards Steve ================================================ This e.mail is private and confidential between Multiplay (UK) Ltd. and the person or entity to whom it is addressed.
