Subject: (2.4.1-ac15) Wont set using_dma = 1 with hdparm
Date: Fri, 16 Feb 2001 12:56:52 -0500 [thread overview]
Message-ID: <3A8D69E4.7DC6EED6@penguinfarm.com> (raw)
With 2.2.18 I can set using_dma = 1 with hdparm on my Dell Inspiron
8000, I cannot with 2.4.1-ac15, so my HD works about 1/3 the speed with
2.4.1.
[root@jkd junfan]# hdparm -I /dev/hda
