I runned memtest86 on opteron + 4GB + tyan k8s s2880.

Many errors like the following were printed.



				cache	ECC	Test	Errors	Ecc error
				on	off	std	842	0

Tst	Pass	Failing Address		Good	 Bad	  Err-Bits	Count	Chan
4	2	0007209d628 - 18248MB	fffffbff 00000400 ffffffff	1
					00080000 fff7ffff ffffffff
					00040000 fffbffff ffffffff
					00020000 fffdffff ffffffff


A strange thing is that Err-Bits are always ffffffff,
and ECC is reported off, although it is on.
