  >Release:	FreeBSD 5.1-CURRENT i386
  >Environment:
 System: FreeBSD 5.1-CURRENT JPSNAP from 11-Jun-2003
 	FreeBSD 5.1-RELEASE is also affected by this bug
 
 	Compaq ProLiant 1850R with Smart Array 221 controller
 
  >Description:
 	Machines with ida(4) supported hard disk controllers will panic
 	on boot in ida_construct_qcb() as GEOM starts inspecting the first
 	disk on the ida controller.  Panic does not occur with ida(4) driver
 	disabled.
 
 	Last message before panic on verbose boot is:
 	GEOM: new disk idad0
 
 	DDB trace at panic shows:
 	ida_construct_qcb()
 	ida_submit_buf()
 	idad_strategy()
 	g_disk_start()
 	g_io_schedule_down()
 	g_down_procbody()
 	fork_exit()
 	fork_trampoline()
 
 	Panic is:
 	Fatal trap 12: page fault while in kernel mode
 	supervisor read, page not present
 	pid is 4 (g_down)
 
 	The panic occurs on ida_construct_qcb+0xca: movzbl 0x5c(%eax),%eax
 	which looks very much like the spot where this function bzero()s
 	the hardware qcb.
 
 	This was previously reported on the current mailing list by
 	Ventsislav Velkov <veno@evrocom.net> on 31 March 2003
 	(Message-Id: <006401c2f776$d16f0230$23f00ad9@beatle>) on similar
 	Compaq hardware.  It is likely that this bug has existed
 	at least since that time.
  >How-To-Repeat:
 	Attempt to boot 5.1-RELEASE or 5.1-CURRENT SNAP's (either floppy or
 	CD) on systems with ida(4) supported hardware with at least one
 	volume configured on the ida controller.
 
  >Fix:
 	Unknown.

 Please close this PR.  This bug has been refiled (properly) with 
 send-pr as kern/53245.
 
 My apologies for the extra overhead, I didn't think the mail client 
 would butcher the message so badly that gnats couldn't understand it.
