SubjectDMA problem with 2.4.21 and 2.4.22-rc1
Hello,

[Please cc me in on any replies]


I am having problems getting a box into DMA mode with 2.4.21 and
2.4.22-rc1:

[root@baloo:~]# hdparm -d1 /dev/hda

/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)


Relevent dmesg stuff:

Uniform Multi-Platform E-IDE driver Revision: 7.00beta4-2.4
ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx
hda: C/H/S=19158/16/255 from BIOS ignored
hda: WDC WD400JB-00ENA0, ATA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hda: attached ide-disk driver.
hda: host protected area => 1
hda: 78165360 sectors (40021 MB) w/8192KiB Cache, CHS=77545/16/63


Any ideas?


Thanks!
