Hi, I rebuilt GENERIC.MP from cvs (current 4th June 2011). This crashed on boot. I reverted to old bsd.mp from April this booted. I downloaded bsd.mp from a mirror site this booted (date 14th May 2011). I downloaded a more recent bsd.mp from ftp.openbsd.org (4 June 2011 GENERIC.MP #57), this crashed on boot in the same place as built from cvs. Below I have typed from screen the panic.
