Well, either that or I need an older kernel. It was also fixed in 2.6.20, for which I think there was a ready-made Slax distribution. On another topic, trying 2.6.20 in whatever Slax distribution it was, an Intel ICH7M had DMA enabled on both /dev/hda and /dev/hdc. I understand that the change which was made shortly after that is considered to be by design not a bug. In 2.6.20 I didn't even have to type a "combined_mode" parameter, it just worked. I understand that the addition and subsequent deletion of the "combined_mode" parameter are considered to be by design not bugs. But it is not at all pleasant that my /dev/hda runs at 1.3 megabytes per second in 2.6.24.3 and later, when it used to run at 45 megabytes per second in 2.6.20. Yeah I know libata is supposed to solve all this stuff. Removed some bugs and added others. I can't go newer than 2.6.24.3 until I find a version where TASKFILEs start working again. There might not be one. Yeah I know libata is supposed to solve all this stuff. I wonder how much time I'll need and how many varieties of hardware I'll have to buy to see if it's really fixed. -------------------------------------- Power up the Internet with Yahoo!
