Hi, I'm seeing a number of these oopses in which a process that was somewhat busy gets killed, on a 2.6.24 + ovz005.1 (custom compiled but no other patches). See below. So far no kernel panic, but obviously useless for a production setup. The machine is 4-way quad-core Opteron, recent build. Do you need more information? (lspci output attached) Suggestions to fix this would be much appreciated. Failing to fix this, I'd be patching Areca drivers on latest 2.6.18 OpenVZ kernel to be able to use this box, but would really prefer to get the new release working instead.
