do you have a real serial console hooked up to the machines? more specifically, can you break into ddb when the machine breaks and get a trace?
i use carp on vlans on lacp trunks on top of myx(4) and em(4) "quite a lot" without trouble, so its likely to be bge(4) if you ask me. unfortunately that means its my fault or responsibility. if you could get a trace to verify, that would be much appreciated. cheers, dlg On 05/05/2013, at 4:11 AM, Loïc Blot <loic.b...@unix-experience.fr> wrote: > Hello misc. > On thursay i have upgraded one of our BGP border routers to OpenBSD 5.3, > and i was pleased to get the BCM5720 working.
