I'm still working on the generic kernel (will run it for the first time
tonight and the next few nights if it doesn't die on day one) but last
night with:
NetBSD 4.99.72 (XEN3_DOM0) #7: Sat Aug 23 10:08:58 EDT 2008
kovert%saidin.omniscient.com@localhost:/usr/obj/current/amd64/amd/guinness/usr/src/os/NetBSD/src/sys/arch/amd64/compile/XEN3_DOM0
total memory = 768 MB
(checkout earlier that day), with xen deamons running, I got what's below.
please let me know if there's more debugging I can stuff in to try to
narrow it down more.
thanks,
-Todd
