On my onboard pmac controller, it either hangs, with "lost interrupt" being repeated, or resets ide0. I thought that it might be because you've changed DMA_TIMEOUT to 100 from 500. When I recompiled with 500 again, it didn't change anything. The driver pmac.c simply cannot get a dma, and doesn't have multicount enabled. \LaShI -- Debian GNU/Linux 3.0 (Sid) (ibook2,powerpc), kernel 2.4.20-ben1-xfs Grub first, then ideals. -- Bertolt Brecht <[EMAIL PROTECTED]> ICQ: 7181075 pub 1024D/CC1F67BC 2002-06-03 Menaka Lashitha Bandara (Freedom!) <[EMAIL PROTECTED]> Key fingerprint = 1874 5597 C754 5209 0A7D 4DA6 9112 5D0E CC1F 67BC
