Quoting Rusu Silviu <bsdgroup.md@gmail.com> (from Thu, 26 Mar 2009 15:53:32 +0200): >> >> Plese run nero within ktrace and provide the output of linux_kdump.

I don't remember to have seen something on the emulation@ list. If there would have been something, I would have reacted the same as for you (kdump + analysis).
