>Description:
	Tested on multiple PC's Dell Gx260 & GX400's
	
	When Heavy I/O occurs on the second or third IDE (ATA) drive the 
following occurs:

	ad1: TIMEOUT - WRITE_DMA retrying - (2 tries left)
	ata0 : resetting devices
	GEOM: destroy disk ad1 dp=0xc2e36860

	Fatal trap 12: page fault in kernel mode
	cpuid=0;apic id=00
	fault virtual address	= 0xdeadc0ea
	fault code		= supervisor read, page not present
	instruction pointer	= 0x0: 0xc0633839
	stack pointer		= 0x10: 0xce6a7c14
	frame pointer		= 0x10: 0xce6a7c34
	code segment		= base 0x0, limit 0xfffff, type = 0x1b
				= DPL 0, pres 1, def32 1, gran 1

	processor eflags	= interrupt enabled, resume, IOPL = 0
	current process		= 2 (g_event)
	kernel: type 12 trap, code = 0
	stopped at g_slice_access+0x59: movl 0xc(%ecx),%eax
