I don't ;-) - I lived w/o IDE DMA until now so I guess I'll survive for another while. Thanks for the help, though. I will try again with ALSA+PIO later in the 2.6.0-test stage, when the other aspects (fb and usb) will more-or-less be usable for me for daily use. > Can you do another test here - write to a floppy disk while doing IDE > DMA and see if it also hangs. It works fine (aside of the ancient floppy disk grifting terribly). -- Petr "Pasky" Baudis .
