You need to apply the latest set of patches to 2.4.8p1 if you intend using dmasound - AFAIK the BK version has a reference to an obsolete function. Ben's tree has the latest patches (apart from the Power Computing stuff - but that doesn't affect you). If all those are 'true' as it were - can you confirm it is dmasound_pmac() ? with the latest set of patches it is *supposed* to be much more friendly to non-awacs chips (doesn't make them work, but is supposed to ignore stuff it doesn't understand...). If that's not the case I want to fix it... It's also puzzling in a way because dmasound_pmac doesn't try to do DMA unless you do SysBeep() or output a sound. Until then the only regs it should touch are in mac-io. ---- 2.4.8-p1 is fine on 9600/233, g3/beige & g4/500/sawtooth (but these all have AWACS or Screamer). Haven't tied the Lombard yet (but don't expect any difference really). ciao, Iain. ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
