Hi, happy sunday to all. I has noted that with the kernels 2.5.46 and 2.5.49, the program hdparm have this output: HDIO_SET_DMA failed: Operation not permitted But with my "emergency" kernel in the same system, 2.4.16, hdparm works fine turning DMA beetween 0 (off) and 1 (on). Where can be the diference?. It is a bug in the development kernels serie?, or maybe a wrong configuration file?. Waiting your answers. TIA. Jose. Debian GNU/Linux 'Sid' Kernel 2.4.19 Ext3.
