Hi there, I am not able to enable DMA for my DVD drive. When I issue 'atacontrol mode 1 UDMA100 XXX' and access the drive, first the drive access hangs, and after a view seconds the machine locks up completely. This also hold true for all other DMA modes. I am running FreeBSD 5.2 on a Fujitsu-Siemens Amilo A Notebook. I would send more info about the ATA/IDE controller, and the error messages but I don't know, how to get to this info. BTW: I know that DMA works for this drive. I have got it working at least with linux 2.4.22, althought I also had alot of DMA problems with other versions, so I suspect the hardware (controller) is flakey. Any help is appreciated. Here follows some output from dmesg:
