Package: linux-image-2.6.12-1-686-smp
Version: 2.6.12-6
Severity: normal
With this linux-image, DMA does not work with my cdrom burners. If I
try to enable it, I get the following message:
morpheus:~# hdparm -d1 /dev/hdb
/dev/hdb:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
I also have a custom built 2.6.12.2 kernel, with DMA working with both
cd-r/rw drives. If anyone is interested in seeing my .config to find
out what modules need to be added, I will gladly send it to them. I am
not sure myself how to figure out what the missing kernel module/option
is.
