Bug 25215

This is a repeat of a similar problem that I reported earilier. http://www.FreeBSD.org/cgi/query-pr.cgi?pr=22762

When kernel with Adaptexc 274X (EISA) boots, it crashes soon after initializing the SCSI Disks. The generic kernel works as did the kernel from the previous fix.

How-To-Repeat: 
ok ?
Available commands:
  reboot           reboot the system
  heap             show heap usage
  bcachestat       get disk block cache stats
  boot             boot a file or loaded kernel
  autoboot         boot automatically after a delay
  help             detailed help
  ?                list commands
  show             show variable(s)
  set              set a variable
  unset            unset a variable
  more             show contents of a file
  lsdev            list all devices
  include          read commands from a file
  ls               list files
  load             load a kernel or module
  unload           unload all modules
  lsmod            list loaded modules
  pnpscan          scan for PnP devices
ok boot
