Compiling most recent sources of CURRENT with Revision: 247040 results
in a kernel crash with funny blinking characters on the screen. This
happens on all systems with different amd64 Intel CPU generations at
this very moment.

Last working sources (reverting and booting kernel.old) is in my case

 FreeBSD 10.0-CURRENT #0 r246949: Mon Feb 18 22:18:42 CET 2013

Does anyone also experience this?

Another remote experimental box, equipted with a Intel Q6600 CPU, is
crashed, I have to investigate this when I get to the lab later. It
seems not to be related only to Sandy-Bridge-E/Ivy-Bridge CPUs.
