Greetings,

Thank you for tracking down and working on this issue; I've installed the new kernel:

Linux foobar-desktop 2.6.31-6-generic #25~lp410198apw1 SMP Tue Aug 11 13:35:31 UTC 2009 x86_64 GNU/Linux

With a vblade running on another machine (on the same broadcast network), ran 'modprobe aoe' and we're seeing an oops:
