I keep getting this error on in /var/log/messages:
Jan 9 01:07:43 mythbox kernel: hda: dma_intr: status=0x51 { DriveReady
SeekComplete Error }
Jan 9 01:07:43 mythbox kernel: hda: dma_intr: error=0x84 {
DriveStatusError BadCRC }
"insmod saa7127 enable_output=1 output_select=0 test_image=1" produces
the color bars like it is supposed to. But when I do dd if=/dev/video
of=/dev/video16 bs=64k to test my framebuffer I get nothing. Are these
DMA errors usually enough to cause nothing at all to come out of the
framebuffer?.
I do have a Abit KT7 which is the KT133 chipset and I see that is known
to have problems with DMA. For those of you that fixed this issue how
did you do so. I already tried a shorter cable. I also tried going
back to a 40 wire cable instead of the 80 wire I was using. I also
tried disabling DMA with hdparm -d0. I am running out of ideas and am
contemplating how I want to get around this. Not sure if I should just
get a new mobo or what. I am pretty confident the drive is good. Any
suggestions are welcomed.
