Subject: 2.4.19pres and IDE DMA
Date: Thu, 02 May 2002 13:41:13 -0700 [thread overview]
Message-ID: <3CD1A469.9040605@rackable.com> (raw)
I'm having issues with a Tyan 2720 and post 2.4.18 boards with a
Maxtor 4G120J6. Under 2.4.18 I can turn on dma via "hdparm -d 1".
Under 2.4.19pre7 I get "HDIO_SET_DMA fail ed: Operation not permitted".
On a side note the same thing occurs with the RH 2.4.18-0.13 kernel.
It appears both kernels merged an ide update from the ac kernel line.
PS-There is also some issue with a resource conflict that occurs under
every kernel I've tried.
2.4.18:
bash-2.05# hdparm -d 1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
using_dma = 1 (on)
bash-2.05# hdparm -d /dev/hda
/dev/hda:
using_dma = 1 (on)
bash-2.05#
2.4.19pre7
root@dev30> /sbin/hdparm /dev/hda
/dev/hda:
multcount = 16 (on)
I/O support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 238216/255/63, sectors = 240121728, start = 0
busstate = 1 (on)
root@dev30> /sbin/hdparm -d1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA fail ed: Operation not permitted
using_dma = 0 (off)
