Tried various shedulers, but didn't help. With kernel 2.4.22-ac4 I > had about 37mb/sec, now only 20mb/sec... I haven't problem with the speed. I'd like to set up DMA to the disk and the -d switch (using_dma) causes the panic. With vanilla 2.6.0-test9 everything works fine, no speed problem. But if I boot up with -mm1, I have to work without DMA on hde. And another interesting thing: hdparm -d1 /dev/hdd works fine, so the problem is somewhere in the siimage driver. I don't know exactly what changed, but something has been corrupted around the driver. IroNiQ -- Krisztian VASAS
