>Description:
      Some change in between aug the 31st en September the 6th
prevents my system from booting; I have both SCSI and ATA disks,
system boots from SCSI disk.
I get :
F1 BSD
F2 DOS
F5 drive 1

immediately after executing /boot/loader system spontaneously reboots

saved loader.old from Aug 31st works OK
loader from Sept 06 already failed
current loader still fails
>How-To-Repeat:
      make installkernel && make installworld && mergemaster &&reboot
>Fix:
         type F5 during boot then :

   Invalid partition
   No /boot/loader

   FreeBSD/i386 boot
   Default: 1:da(1,a)/kernel
   boot:

   Invalid partition
   No /kernel

   boot:

manually type 
  0:da(0,a)/boot/loader.old

et voila
