Date: Sun, 13 Jul 2003 09:33:29 +0200 [thread overview]
Message-ID: <20030713073329.GA5595@tangerine> (raw)
Hi,
This is part of dmesg :
...
Journalled Block Device driver loaded

When I try to set dma on on either of the disks, I get the following:
[root@debian-f5ibh] ~ # hdparm -d1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
[I'm not on the list, please cc to me]
