George's comments would agree with the kernel messages description of the
problem:
		IO err in push
		File: 		/sys/vm/vm_swp.c
		Routine:	swdone
		Problem:	A hard I/O error occurs as a page kluster
				is being transferred.

				The routine detected a hard I/O error had
				occurred as a page kluster was being
				transferred.  This error typically indicates
				a hardware problem.
