Hi,
Slackware 10
When I switch to kernel 2.6.7 I get the following error message on boot:
* Warning: The dma on your hard drive is turned off. * * This may really slow down the fsck process. *
Apparently with the command "hdparm -d /dev/hda" dma is turned on.
Where in /etc/rc.d if that is the place do I put this command?
However, giving the command from the console as root after booting I get:
setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off)
How to resolve?
Thanks & regards
What kind of hard drive and IDE chipset does it have? I know some drives were recently added to a no-DMA blacklist for behaving badly. Normally, dma is supposed to be enabled by default, and only disabled when a known-bad hard drive or IDE controller is found.
On my Slack 10.0 server, I put hdparm in rc.local. My rc.local:
(most of the disk storage is on SCSI drives, /dev/hda is just the boot drive due to a POS BIOS that can't boot off of expansion cards)
#!/bin/sh # # /etc/rc.d/rc.local: Local system initialization script. # # Put any local setup commands in here:
# enable 32-bit mode, turn on APM, set spindown for 1 hour, # unmask IRQ's, nd set the keep-settings flag for /dev/hda hdparm -c 1 -B 128 -S 242 -u 1 -k -q /dev/hda
