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.
